Please visit https://bitbucket.org/kayontoga/rattle/commits/ for the
definitive list of changes. This NEWS file will only update major
releases going forward.

rattle 5.3.6 20200501 Graham.Williams@togaware.com

  * Bug fixes: predict for xgboost; ignore NA in checking for binary
    class; varImp log handling.
  
rattle 5.3.1 20191123 Graham.Williams@togaware.com

  * Convert datasets to be tibbles, moving towards tidyverse
    compliant. Require tibble package. Also require bitops as needed
    when loading a tibble as an RDataset into Rattle.

rattle 5.3.0 20191123 Graham.Williams@togaware.com

  * Cleanup and prepare for CRAN release.

rattle 5.2.8 20191016 Graham.Williams@togaware.com

  * Remove dependencies on archived packages RGtk2Extras and playwith.

  * Bug fix View Data button to just call R's View() rather than a
    glade data view or RGtk2Extras data viewer.

  * Update weatherAUS dataset with most recent weather observations
    now with 166,310 data points.

rattle 5.2.7 20190407 Graham.Williams@togaware.com

  * Bug fix - the export PMML file dialog stopped working - perhaps a
    RGtk2 update. It was using glade. Instead create the dialog
    directly in code. Reported by Julian Ochoa.

rattle 5.2.6 20190331 Graham.Williams@togaware.com

  * Bug fix - rattle was incorrectly specifying load instead of open
    in a GTK file chooser which did not work on an RGtk2
    update. Reported by Dave Arnold and Eric Mattys.

rattle 5.2.5 2018-09-26 17:23:00 Graham.Williams@togaware.com

  * Add labels to var imp plot for conditional forest.

rattle 5.2.4 2018-09-23 10:43:12 Graham.Williams@togaware.com

  * Bug fix in getCategoricVariables() when no target is defined and
    include.target is true.

  * Bug fix in kmeans stats when the data is scaled. Reported by Caleb
    Terrel Orellana.

rattle 5.2.3 2018-09-17 10:43:12 Graham.Williams@togaware.com

  * Bug fix random forest Errors and OOB ROC buttons are not available
    for conditional random forests. Reported by Cristina Acasuso.

rattle 5.2.2 2018-09-14 21:12:31 Graham.Williams@togaware.com

  * Bug fix xgboost response command as it is now including two target
    columns from the previous bug fix which added target into
    predict. Reported by Aous Alex Abdo.

rattle 5.2.1 2018-08-19 20:31:55 Graham.Williams@togaware.com

  * Improve handling of Missing RGtk2 message.

    Dubassarsky.

rattle 5.2.0 2018-08-12 15:17:12 Graham.Williams@togaware.com

  * Remove dependency on RGtk2 and check it dynamically. Rattle has
    more functionality than just the GUI yet we force installation of
    RGtk2 which is problematic on some platforms.

  * Return the datasets to rattle package. Has caused too much
    confusion as a separate package.

rattle 5.1.6 2018-08-12 15:17:12 Graham.Williams@togaware.com

  * Bug fix for new rpart.plot with roundint= handled automatically.

    hierarchical clustering. Results in errors for the weather
    dataset. Reported by Tony Nolan.

rattle 5.1.3 2017-10-29 21:25:08 Graham.Williams@togaware.com

  * Bug fix: xgboost evaluate to score file failing. Needs target in
    the precit command to succeed! Actually needs a fix to
    predict.xb.formula but include a work arond for now. Reported by
    Dwight Barry.

rattle 5.1.1 2017-09-08 16:08:03 Graham.Williams@togaware.com

  * Update and bug fix to riskchart for risk AUC as provided by
    Cameron Chisholm.

rattle 5.1.0 2017-09-04 08:20:34 Graham.Williams@togaware.com

  * Resolve all final check tests, redo testing, and release to CRAN.

rattle 5.0.19 2017-07-10 15:14:34 Graham.Williams@togaware.com

  * Debug the xgboost interface - limited to binary classifcation
    tasks for now. Key is that the R code is exported and can be used
    as a template for extended modelling.

rattle 5.0.18 2017-06-27 06:54:48 Graham.Williams@togaware.com

  * Tune Boost interface.

rattle 5.0.17 2017-06-24 10:58:15 Graham.Williams@togaware.com

  * Move the dataset from the rattle package to a separate rattle.data
    package in line with CRAN guidelines to have a separate package
    for slower changing datasets of considerable size. This will also
    allow the option to provide further datasets for rattle as part of
    that package.

  * Use weather.csv as the sample for both R and Microsoft R as
    weatherAUS.csv is too large to include in a CRAN package.

  * Ensure strings are treated as categoricals on loading the data
    with Microsoft R so as to conform to read.csv() and to be
    consistent with the non-Microsoft R version of Rattle.

rattle 5.0.16 2017-06-17 08:18:26 Graham.Williams@togaware.com

  * Update the weather dataset from the Australian Bureau of
    Meteorology and add sample weatherAUS.xdf to the package to
    be loaded as the default example when Microsoft R is
    detected. XDF is a file system based data format used by
    Microsoft R to handle datasets of *any* size rather than
    being limited by available computer RAM.

rattle 5.0.15 2017-06-17 07:48:30 Graham.Williams@togaware.com

  * Merge RevoScaleR (Microsoft R) support for NeuralNetworks and
    KMeans from Microsoft India Data Group team.

rattle 5.0.14 2017-06-12 13:12:00 Graham.Williams@togaware.com

  * Merge support for RGtk2 2.20.31 and 2.20.33 to resolve the
    bug across all installations.

rattle 5.0.13 2017-06-05 16:51:18 Graham.Williams@togaware.com

  * Merge initial xgboost support from Zhou Fang. This is in
    testing and will become the default boosting algorithm soon.

rattle 5.0.12 2017-05-30 13:52:51 Graham.Williams@togaware.com

  * Bug fix call to errorMatrix() where counts= is not count=.

  * Bug fix to evaluate where respcmd for random forest has
    disappeared when incorporating MRS updates.

rattle 5.0.11 2017-05-26 17:43:01 Graham.Williams@togaware.com

  * RGtk2 version 2.20.33 released and caused some issues with
    Rattle. Heuristic test of libglade/GtkBuilder began failing
    and retval no longer used for obtaining returned values. 

rattle 5.0.10 2017-04-30 13:57:16 Graham.Williams@togaware.com

  * Review predict.hclust() to use cutree() by default and
    predict.kmeans() for a Euclidean distance approach as an
    option. Bug report by Hamed Mamani.

rattle 5.0.9 2017-04-14 13:17:33 Graham.Williams@togaware.com

  * Introduce a checksum for R datasets (data.frames) so that we
    can identify when a user has changed the R dataset outside of
    Rattle, and have the new version loaded.

rattle 5.0.8 Graham.Williams@togaware.com

  * Incorporate updates for ggratpR(). Close to functional and so
    it is nearly ready for release.

rattle 5.0.7 2017-03-05 18:13:22 Graham.Williams@togaware.com

  * Support for rxDTree, rxDForest, rxGlm, rxLinMod. Thanks to

  * Update weatherAUS dataset.

  * Bug fix for sample XDF dataset - if smaller the
    crv$xdf_preview then load the whole dataset into memory.
       
  * ggVarImp now has n= option for the top n variables. Also
    supports xgb.Booster models from xgboost.

rattle 5.0.4 Graham.Williams@togaware.com 2017-02-04 15:15:34 Graham Williams

  * Bug fix ggVarImp to work for randomForest() when importance=FALSE.

  * Add log= option to ggVarImp() for a log scale.

rattle (2.6.26) unstable; urgency=low

  * Replace .path.package with path.package as requested by Ripley. The
    hidden version will disappear soon and the new version has been
    available since 2.13.0.

  * Update boost help to note that it is available only for binary
    classification.

  * Default stemming for textmining of a corpus is no active if the
    Snowball package is available.

  * For Advanced Graphics introduce a dendrogram plot using ggplot2.

  * Various text mining improvements. Bug fix in checking if data needs
    reloading.  Support checking if corpus needs reloading.  Add extra
    cursor and status bar messages.  For corpus, set default folder to be
    getwd().  Check for mismatch between number of docs in corpus and the
    number of targets in .targets.csv. For the Corpus file dialog, do not
    offer folder creation.

  * Remove macosx special rattle.ui. The ubuntu specific text no longer
    appears in the saved ui file.

  * Internally: Move rattleGUI to crv from crs. The crs is saved as the
    state, and this was confusing the GUI on a project restore.  Had to
    ensure we restored rattleGUI with the current rattleGUI - this fixes
    loadProject bug.  Also, in Load project, filter on .RData not .Rdata.

  * Add newdata= to call to predict, in line with the standard approach by
    party (reference Torston). Remove the OOB= for predict for
    cforest. With a new dataset OOB makes no sense. It was in there
    because newdata= was not being used and positionally having issues.

  * Update fancy rpart plot to reduce colour intensity for printing and a
    nicer tree structure. Add all class probs to fancy tree.

  * Define paste0 if it is not defined. It was introduced in 2.15.0 but is
    too early to assume the world is with us.

  * Replace siatclust with weightedKmeans.

  * Bug fix in OOB plot when impute is off - need to omit missing values.
    Update message regarding random forest and na.omit() removing all
    rows, noting the option to use na.roughfix().

  * Fix bug identified by Brian Feeny 121209 - score a RF test dataset
    without a target variable tries to add one in all NA but fails if it
    is the last variable.

  * Experimentally add Deducer's data.viewer to View data.  Ensure we ask
    user if when using Plot Builder it is okay to create a dataset in
    their work space. Hopefully keeps us in line, if not strictly in
    copmliance, with CRAN policy.

  * Remove SVG support - RSvgDevice is no longer available.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 16 Mar 2013 13:27:05 +1100

rattle (2.6.25) unstable; urgency=low

  * Review all of the code and remove two instances of using copyrighted
    code without attribution. One was a copy or print.rpart, where rattle
    added a translation wrapper to the text message. Another was code
    copied from the Internet from David Hand - use the Hmeasure package
    now. Note in drawTreeNode() reference to the original author and lack
    of copyright. Note author in Authors@R. ggcorplot is now available
    from Deducer. Remove it from Rattle. Replace Hand measure with
    HMeasure from hmeasure. Add Mark Vere Culp as aux author. Remove
    commented out code. Remove lss and cranSearch - not really part of
    Rattle.

  * Update to new style Authors@R.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 23 Jan 2013 13:12:43 +1100

rattle (2.6.24) unstable; urgency=low

  * Bug fix for box plot using ggplot2.

  * Finish the implementation of riskchart using ggplot2 to mimic the old
    version of risk charts.

  * Remove copied code from print.rpart, known as rattle.print.rpart, and
    originally used without proper credit to Brian Ripley, but no longer
    required. Use his original versoin from rpart itself, though lose the
    translations.

  * Migrate to a cleaner structure for managing the source package locally
    at togaware.

  * Bug fix fancy rpart plot to handle regression as suggested by Yana
    Kane-Esrig.

  * For arules, add option to specify minimum length.

  * Update to new version of RGtk2Extras' dfedit, without a pretty_print
    option. Also able to assign result into crs$dataset now.

  * Remove two instances of global variable assignments. Temporarily
    remove PlotBuilder and scoring of manually entered datasets.

 -- Graham Williams <Graham.Williams@togaware.com>  Tue, 11 Dec 2012 06:45:50 +1100

rattle (2.6.21) unstable; urgency=low

  * Retain depend on R > 2.12.1.

  * Ensure rattle.togaware.com repo is maintained.

  * Better detect arules error message for duplicate items in a basket.

  * Update ggplot2 calls to conform to 0.92. Also turn advanced graphics
    on by default. Implement risk charts using ggplot2.

  * Start introducing suppressPackageStartupMessages to avoid excessive
    messages in the console.

  * Do AUC only for binomial targets.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 10 Sep 2012 19:27:42 +1000

rattle (2.6.20) unstable; urgency=low

  * Because of use of globalVariables Rattle now depends on R >=
    2.15.1. However, check this conditionally to retain backward
    compatibility for now. Reported by Uwe Ligges.

  * For show arules, eval in global environment else it does not show the
    rules. Reported by Tania Churchill.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 23 Jul 2012 02:27:18 +1000

rattle (2.6.19) unstable; urgency=low

  * Depend on weightedKmeans rather than siatclust.

  * Bug fix: correlation plots stopped working.

  * Bug fix: ggcorplot use of size_scale started failing. Perhaps because
    of new version ofggplot2.

  * Bug fix: notice when a restored project does not have a filename set.

  * Fix some logic errors in rf.

  * Add 0,0 point to evaluateRisk.

  * Make risk, recall, precision as default names in risk chart.

rattle (2.6.17) unstable; urgency=low

  * Add a log10 transform to the GUI, R10 prefix, add tooltip, handle it
    in pmml, create new rattle_macosx.ui. Suggested by Christophe Klopp.

  * Bug fix usage of believeNRows - it was being ignored from the GUI, but
    is now acted upon. Reported by Andrew Elliott.

  * Add ggplot2 box plots to Advanced Graphics option.

  * Remove the timestamp messages.

  * Update pmml to handle randomForest and rattle to export to pmml.

  * Bug fix in naming the dataset when it is editted.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 19 Feb 2012 21:49:45 +1100

rattle (2.6.16) unstable; urgency=low

  * rattleInfo() now also notes if rattle itself needs upgrading.

  * Bug fix in show association rules. It now works again.

  * Forgot to include rescale.by.group() in NAMESAPCE.

  * CITATION to the book rather than the article. That is a more
    definitive resource, though not freely available.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 24 Dec 2011 15:35:21 +1100

rattle (2.6.15) unstable; urgency=low

  * Bug fix for Mac OS/X on 2.14.0 with a call to set.cursor failing
    because the textviews do not yet exist. Problem is that the
    addFromFile for the GUI is generating a Warning that seems to now stop
    the file being loaded. Removing the particular XML elemnts causing the
    warning (one ubuntu_local and 4 GtkTreeSelections) "fixes" the
    problem.

rattle (2.6.12) unstable; urgency=low

  * Ensure the data partitions that are specified are appropriate. Also
    allow some flexiblity in specifying: 70 or 70/30 or 70/15/15. For the
    first two the training is 70% and testing is 30%. For the third,
    validation is 15% and testing is 15%.

  * Update text mining support for lates version of tm.

  * rattleInfo() was incorrectly counting the unmber of packages listed.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 23 Oct 2011 06:00:16 +1100

rattle (2.6.11) unstable; urgency=low

  * Use listAdaVarsUsed in Rattle.

  * Use fancyRpartPlot in Rattle.

  * Note rattle.ui requires gtk > 2.16, not > 2.20. Otherwise fails to
    start on Mac OS/X.

    as in the Settings menu.

  * Add common name and crv constant for ewkm.

  * fancyRpartPlot has optional main title as empty string.

  * biclust now reports a biclust built rather than reporting a kmeans
    built.

  * Add weights plots for ewkm from siatclust.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 11 Sep 2011 17:08:18 +1000

rattle (2.6.9) unstable; urgency=low

  * AdaBoost now also reports which variables are used in the collection
    of trees built, and the number of trees in which a variable
    appears.

  * Add setupDataset and whichNumeric to support encapsulation of data
    mining objects.

  * Add a fancyRpartPlot so my fancy rpart tree is available outside of
    the rattle GUI.

  * Correct the textview information relating to confusion matrices.

  * Add doRiskChart to simplify using the risk charts.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 04 Sep 2011 21:03:32 +1000

rattle (2.6.8) unstable; urgency=low

  * Ensure ggplot2 loaded before plot ctree.

  * Handle probability predictions for ctree and cforest in evaluation.

 -- Graham Williams <Graham.Williams@togaware.com>  Tue, 26 Jul 2011 22:03:47 +1000

rattle (2.6.7) unstable; urgency=low

  * Add support for the entropy weighted k-means subspace clustering
    algorithm from the ewkm package.

  * Ensure rattle can load with only the base package installed (so
    install.packages is prefixed with utils:::).

  * Migrate from using installed.pacakges() since it can be very slow on
    MS/Windows.

  * Add an experimental dataset option to the command line call to rattle.

  * Allow a bygroup to be used for any numeric transform.

  * Add a plot for association rules.

  * Display a ggplot2 scatterplot if advanced plots is enabled.

  * rattle:::executeExplorePlot made more friendly for calling from
    outside of Rattle.

  * Tidy up the rattleInfo manual page.

  * Master Makefile should respond with help if no target specified.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 18 Jul 2011 06:53:47 +1000

rattle (2.6.6) unstable; urgency=low

  * Settings/Tooltips should be shown as TRUE.

  * Add Settings/GGPlot2 to enable enhanced graphics (generally using
    ggplot2) where they have been implemented.

  * Implement a ggplot2 pairs plot (scatterplot) as the plot to use when
    ggplot2 is enabled and under Explore/Distriubtions no variables are
    chosen to be displayed. Uses ggcorplot from Deducer.

  * Implement use of rpart.plot's prp() when ggplot2 is enabled.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 09 Apr 2011 22:16:29 +1000

rattle (2.6.5) unstable; urgency=low

  * Add rattleReport() - report on current state of rattle modelling.

  * Restore the ByGroup option for now until it can be coded for the about
    transforms.

  * Deal with UTF-8 encoding of Japanese filenames in data and evaluate,
    using iconv.

  * Be sure to include http:// in web links, though on MS/Windows still
    not working: Could Not Show Link... No application is registered as
    handling this file

  * On loading a dataset, convert any character variables to be
    factors. Rattle does not handle character variables, so the
    translation seems appropriate.

  * Association rules status bar was refering to decision
    trees. Fixed. (Pointed out by Xiaobo Gu)

  * Fix an introduced bug in handling of categorics in numeric transforms.

  * Fix a bug where imputation for a categoric with class "ordered" and
    "factor" was treating it as a numeric (because "ordered" is not
    "factor").

  * Some Help menu items under Test were not loading the required package
    and thus were not displaying the help.

  * Only do crosstabs when we have categoric variables.

  * Updated translations.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 13 Mar 2011 16:46:20 +1100

rattle (2.6.4) unstable; urgency=low

  * Confusion matrices transposed to conform to what most people exect:
    Actual is on left and Predicted is on top. Retain the name as Error
    Matrix in Rattle for now.

  * Use different pch for a dotchart.

  * Include the install.packages(rattleInfo()) trick in the output of
    rattleInfo().

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 19 Feb 2011 06:26:09 +1100

rattle (2.6.3) unstable; urgency=low

  * weather.arff Date field should have 'date' data type.

  * The rug plot of histograms is no longer coloured. For large datasets,
    there is much overplotting and so it can in fact be quite misleading.

  * Box plots now use varwidth=TRUE to indicate the distribution of the
    target variable.

  * Bug fix: exportHClustTab should not have a file argument.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 13 Feb 2011 21:42:11 +1100

rattle (2.6.2) unstable; urgency=low

  * Rename rattle.info() to rattleInfo(), modelled on sessionInfo()
    naming. Include available CRAN version of rattle in the output.

  * Ensure connection is closed on pmmltoc export from Rattle.

  * questionDialog needs to not use RGtk2 if RGtk2 is not installed!

  * Emphasise that Rattle is free in loading the rattle package.

  * exportKmeansTab does not require the file argument.

 -- Graham Williams <Graham.Williams@togaware.com>  Wed, 02 Feb 2011 05:46:28 +1100

rattle (2.6.1) unstable; urgency=low

  * When exporting a regression model, be sure to use proper slash (i.e.,
    not the Windows slosh) for log tab record of the command.

  * Add rattle.ui to the google code repository.

  * Remove as many literals as possible from the Log tab - so that
    crs$dataset[crs$sample, c(2:10,14,16:20)] becomes
    crs$dataset[crs$sample, c(crs$input, crs$target)], for
    example. Similarly for the set.seed and other data storing variables.

  * Other Log tab cleanup.

  * Fix bug that caused failure on reading an .xls data file.

  * rattle.info() now returns the list of packages that need updating.

  * In exporting a model as C code, if we are Japanese on Windows then
    note that the encoding is shift-jis rather than utf-8 for some reason.

  * Improve infrastructure for the generation of C code from PMML.

 -- Graham Williams <Graham.Williams@togaware.com>  Thu, 13 Jan 2011 21:50:53 +1100

rattle (2.6.0) unstable; urgency=low

  * Keep track of project names and use as default name to save a project
    to. Suggested by David Cochrane.

  * Add strip.white to the default for reading CSV files. Suggested by
    Robert Muenchen.

  * Bug fix on resetEvaluateTab - Data row was being reset to sensitive
    because model was being toggled.

  * Disconnect Rattle versions from google code revision numbers since the
    revision numbers change each change to the Wiki.

  * Indicator Variables will Ignore the first of the new indicator
    variables. Suggested by Robert Muenchen.

  * Include the Target name in listing of a decision tree as a rule set.

  * On adding to the log when saving a plot make sure carioDevice is
    loaded and the file name path separators are appropriate. Reported by
    Shane Butler 11 Dec 2010.

  * Ensure filename string is UTF-8 when exporting a file, to handle
    Japanese filenames.

  * For nnet, choose a seed so weather generates a non-trivial model.

  * Refer to remapping as recoding in line with commonly used terminology.

  * Default back to showing text on icon for buttons. Seems okay in the
    new version of Gtk.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 11 Dec 2010 13:39:55 +1100

rattle (2.5.47) unstable; urgency=low

  * Add a useGtkBuilder argument to rattle(). If NULL, then heuristically
    determine, otherwise go with the specified choice, if possible.

  * Remove RGtk2, colorspace, and pmml as dependencies. Now dynamically
    check and offer to install. This also helps reduce chance of the
    XML/RGtk2 zlib1.dll bug, and also ensure RGtk2 loads before XML to
    avoid that bug.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 15 Nov 2010 21:50:15 +1100

rattle (2.5.46) unstable; urgency=low

  * Bug fix for fixTranslations.

  * Save weights information in PMML.

 -- Graham Williams <Graham.Williams@togaware.com>  Thu, 11 Nov 2010 19:08:36 +1100

rattle (2.5.45) unstable; urgency=low

  * Check for GtkBuilder handling of the 'requires' tag, and if not
    handled the don't use GtkBuilder.

  * Bump pmml version through 1.2.25 to 1.2.26.

  * Change default nolan groups for a singularity to 50 rather than 99.

  * PMML bug fix when glm and using weights.

  * Move all variable initialisation from .onLoad to .onAttach. This will
    ensure .RData saved (and therefore old) versions of the variables will
    not overwrite the proper versions in a newer release of Rattle.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 09 Oct 2010 08:16:15 +1100

rattle (2.5.44) unstable; urgency=low

  * Add an include.libpath to rattle.info() to provide information about
    where the packages are installed.

  * Check for failed startup of rattle GUI using GtkBuider (because the
    Gtk library installed does not recognise 'requires' and suggest a
    workaround).

  * Condiionally turn toolbar Text (in addition to just Icons) on.

  * For loading spreadsheets, make sure RODBC is available and loaded.

  * Ensure 'ordered categoric' are treated as categoric for Explore,
    Distribution.

 -- Graham Williams <Graham.Williams@togaware.com>  Tue, 05 Oct 2010 18:08:20 +1100

rattle (2.5.43) unstable; urgency=low

  * Ensure gtkBuilder is setting the correct translation domain for the
    interface.

  * Add global option for not showing timestamps: crv$show.timestamp.

  * Add optional arg to newProject to not ask about overwriting a
    project. Default is as previously - to ask.

 -- Graham Williams <Graham.Williams@togaware.com>  Wed, 22 Sep 2010 05:37:53 +1000

rattle (2.5.42) unstable; urgency=low

  * Update rattle.info() to recursively identify all dependencies, report
    their version number and any updates available from CRAN and generate
    command to update packages that have updates available. See
    ?rattle.info for the options.

  * Fix bug causing R Dataset option of the Evaluate window to always
    revert to the first named dataset.

  * Fix bug in transforms where weights were not being handled in
    refreshing of the Data tab.

  * Fix a bug in box plots when trying to label outliers when there aren't
    any.

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 19 Sep 2010 05:01:51 +1000

rattle (2.5.41) unstable; urgency=low

  * Use GtkBuilder for Export dialog.

  * Test use of glade vs GtkBuilder on multiple platforms.

  * Rename rattle.info to rattle.version.

  * Add weight column to data tab.

  * Support weights for nnet, multinom, survival.

  * Add weights information to PMML as a PMML Extension.

  * Ensure GtkFrame is available as a data type whilst waiting for updated
    RGtk2.

  * Bug fix to packageIsAvailable not reruning any result.

  * Replace destroy with withdraw for plot window as the former has
    started crashing R.

  * Improve Log formatting for various model build commands.

  * Be sure to include the car package for Anova for multinom models.

  * Release pmml 1.2.24: Bug fix glm binomial regression - note as
    classification model.

 -- Graham Williams <Graham.Williams@togaware.com>  Wed, 15 Sep 2010 14:56:09 +1000

rattle (2.5.40) unstable; urgency=low

  * Conditionalise useGtkBuilder:
    if windows and R before 2.12.0 then libglade 
    if unix and R 2.12.0 then libglade for now (RGtk2 update needed?)
    all else use GtkBuilder

 -- Graham Williams <Graham.Williams@togaware.com>  Sun, 22 Aug 2010 12:02:00 +1000

rattle (2.5.39) unstable; urgency=low

  * Conditionally use either libglade2 or GtkBuilder for the
    GUI. libglade2 (a separate library to the Gtk+ library) is deprecated
    and as of R 2.12.0 won't be supported on MS/Windows binary builds. The
    default is now GtkBuilder (built into the Gtk+ library), and support
    for libglade2 within Rattle is deprecated. RGtk2 (2.12.18) still has
    issues in its support of GtkBuilder and is being actively worked on,
    but Rattle is currently working around these.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 21 Aug 2010 07:47:43 +1000

rattle (2.5.38) unstable; urgency=low

  * Ensure pmml.ksvm will at least run - though resulting PMML not
    validated.

  * Bump pmml version to 1.2.23

 -- Graham Williams <Graham.Williams@togaware.com>  Fri, 06 Aug 2010 05:56:11 +1000

rattle (2.5.37) unstable; urgency=low

  * The Predictive tab has gone back to being Model. Not sure which is
    best.

  * cranSearch defaults to r-project rather than unimelb.

  * Migrate from RGtk2DfEdit to its replacement, RGtk2Extras.

  * Revert cairoDevice to being a Suggests rater than Depends.

  * Remove redundant CITATION from root of package, as the real one is in
    inst.

 -- Graham Williams <Graham.Williams@togaware.com>  Sat, 31 Jul 2010 14:34:50 +1000

rattle (2.5.36) unstable; urgency=low

  * Add Bill Venables' searchCRAN example code.

  * Improve error message when we find duplicate variable names in a
    loaded file, which might result when there is no header line.

  * Add help item for Projects.

  * On Evaluate with supplied file, use the hdr specified on the Data tab.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 12 Jul 2010 06:43:06 +1000

rattle (2.5.35) unstable; urgency=low

  * Add utility lss function to list object sizes.

  * Add options text entry for SVM to easily allow other options.

  * Better formatting of the Log tab.

  * Use a set.seed for SVM to ensure same model each time.

  * Add option to random forest to impute missing values rather than
    simply ignoring the observations.

  * On Evalaute with supplied file, use the sep specified on the Data tab,
    thus allowing TXT files.

  * On loading a new dataset for evaluation be sure to add in any missing
    columns, and unify the levels.

  * Improve binning documentation.

  * Make RGtk2, cairoDevice, colorspace all dependencies so we can get
    rattle started and then rattle will prompt to install other packages
    that are mssing when it needs them.

 -- Graham Williams <Graham.Williams@togaware.com>  Thu, 01 Jul 2010 15:34:50 +1000

rattle (2.5.34) unstable; urgency=low

  * When a package is missing, there is now the option to install it right
    then, and it continues as normal after it gets installed.

  * Change Suggests to Depends so all used pacakges get loaded on loading
    rattle, in an attempt to make it easier to install Rattle. Then the
    r-cran-rattle package on Debian/Ubuntu will have all required
    dependencies and a normal install.packages will get all dependencies
    also, rather than having to use dependencies=c('Depends',
    'Suggests'). Penalty is it takes 20 seconds to do 'library(rattle)' on
    a server and 90 seconds on a netbook - so revert back to not doing
    this.

  * Ensure the new train/validate/test scneario is saved across projects.

 -- Graham Williams <Graham.Williams@togaware.com>  Wed, 09 Jun 2010 07:04:08 +1000

rattle (2.5.33) unstable; urgency=low

  * Bug fix rf.cmd.

  * Improve scoring functionality: The dataset can have NA's for target,
    and these can now get scored by rf on Evaluate tab. Loading a CSV file
    to be scored no longer needs to have the target column included
    (previously it needed to be there and have non-NA values). Thanks to
    Chris Snijders.

 -- Graham Williams <Graham.Williams@togaware.com>  Mon, 31 May 2010 06:22:54 +1000

rattle (2.5.32) unstable; urgency=low

  * Remove dependency on car - not actually being used at the moment.

  * For random forest, allow sample size text entry as a single integer or
    a list, as per randomForest.

  * Use na.omit with cforest, as is done with randomForest.

  * For randomForest turn subsampling with replacement off since it is
    more likely to produce biased importance measures, as explained in by
    the cforest papers.

  * Fix bug with multiple "contact support" lines in error popups.

  * When showing the randomForest importance values, sort on the accuracy
    measure rather than the Gini measure, since the Gini is biased in
    favour of categoric variables with many categories.

  * ada boost seed should be 42, like all other seeds.

  * Tidy up some ada output.

  * Bug fix - save project for rf failing (looking for rf_sampsize_entry).

  * Remove text from toolbar by default.

  * Change order of Forest/Boost buttons on Model tab.

  * Add tooltips for all toolbar buttons.

 -- Graham Williams <Graham.Williams@togaware.com>  Fri, 28 May 2010 15:47:15 +1000

rattle (2.5.31) stable; urgency=low

  * Add rattle.info() to list information for debugging purposes.

  * Bump pmml to 1.2.22

  * Fixes from wenching.lin@zementis.com: Extension in Header should be
    first element. Coefficients in regression models should not be NA (as
    will be for singularities), but replace with, and so no impact of
    change.

  * Ensure Survival defaults are reset appropriately.

rattle (2.5.30) stable; urgency=low

  * On MS/Windows with Japanese, read.csv needs encoding option set with
    file rather than with read.csv (for UTF-8) but seems okay under other
    scenarios.

  * On MS/Windows with Japanese (UTF-8) the encoding of the variables
    selected for transforming needs to be UTF-8 for much of the process,
    but "unknown" when using Rtxt and sprintf (when substituting the
    variable names) to ensure resulting message is correctly matched for
    encodings.

 -- Graham Williams <Graham.Williams@togaware.com>  Wed, 19 May 2010 09:47:12 +1000

rattle (2.5.29) stable; urgency=low

  * Add the translation file.

  * Fix an Encoding/sprintf issue for Japanese on MS/Windows.

  * Allow crv$NOTEBOOK.MODEL.NAME to be overridden by other packages
    (RStat).

  * When dispatch fails be sure to include the Tab label on which it fails.

  * Ensure HClust Options are re-enabled on loading a project.

 -- Graham Williams <Graham.Williams@togaware.com>  Thu, 22 Apr 2010 06:21:58 +1000

rattle (2.5.27) unstable; urgency=low

  * Further translation fixes. In particular, use Encoding(...getText())
    <- "UTF-8" to ensure strings from the GUI ate UTF-8, and not unknown.

  * Ensure training dataset rather than sample dataset nomenclature is now
    used.

  * Ensure execute button can only be clicked once while it is processing.

  * Survival plot buttons need to be made sensitive as appropriate.

  * For Japanese on MS/Windows do not use monospace font since this ends
    up vertically cenbtering periods and commas (and all other
    characters). Need a fixed width font that does not do this, but for
    now we put up with variable width font.

  * Revert to using only English for all hidden tab labels.

  * Improved identification of current plot number.

  * Bug fix multiple vars selected for asnumeric and ascategoric
    transforms.

    each categoric variable by the target variable. (Luke Lake)

  * Bug fix - improve how we obtain the plot number from the title,
    particularly in the context of translations.

  * Further translation markup.

  * Clean up the use of dfedit.

  * Minor improvement to spacing in Log tab.

 -- Graham Williams <Graham.Williams@togaware.com>  Tue, 30 Mar 2010 21:37:29 +1100

rattle (2.5.25) unstable; urgency=low

  * Start using the RGtk2DfEdit for the View and Edit buttons of the Data
    tab, and the Enter/Score option of the Evaluate tab. RGtk2DfEdit
    provides a spreadhseet like interface to the data. Various data
    editing options are available. Also press = to run an arbitrary R
    command on selected data (e.g. select two columns of data and issue
    the plot command).

  * Add further markup of text for translations.

  * Support specification of the character used for decimal points (to
    suit some European usage).

  * Fix bug in exporting XML - replace & with &amp;

  * Survival plots - split survival chart plot from residuals plots, and
    plot all residuals.

  * Fix logic behind what is greyed out in the Test tab.

  * Revamp the help text, and put into the Rtxt translation framework.

  * Fix the height of the data name widget (the library option was growing
    the width for some reason).

  * For Evaluate, add Full and Enter as dataset options. Enter will pop up
    an editor with the final row from the dataset, allowing you to add
    rows or modify the supplied row. We supply the row so that we have an
    example to work from. Full uses the whole original dataset.

rattle (2.5.23) stable; urgency=low

  * Catch "arules" error in converting data to transactions when baskets
    contain repeated items.

  * When data tab is executed, and so crs$rpart is reset to NULL, always
    remove the Draw/Rules button from the Tree option of the Predictive
    tab.

  * Add code to fix translations that are not being loaded when using
    RGtk2 on MS/Windows. All is okay on GNU/Linux, but RGtk2 seems not to
    get the right locale for loaded Glade file. The fix is to traverse the
    GUI and change all labels, on starting up Rattle. RGtk2 authors tried
    to fix but it remains an issue.

  * Ensure rpart is reset on resetting rattle.

  * Rework handling of tab pages because a Japanese translation on
    MS/Windows is having issues with the following call (nd=notebook)
    nb$getTabLabelText(nb$getNthPage(nb$getCurrentPage())) returning what
    looks like Shift-JIS encoding of the string rather than UTF-8, and
    hence not string matching the expected tab label.

  * Fix spelling errors on help menu and ensure help for all topics is
    covered.

  * For nnet, use MaxNWts=10000 (default is 1000) to allow larger nets by
    default, and capture the error message when this is exceeded and
    better explain what to do.

  * Ensure we don't export an empty dataset when choosing export on the
    data tab.

  * Capture arules error message when there are repeated items in one
    basket, and explain this more clearly.

  * For rpart use information as the default split rather than Gini - makes
    little if any difference.

  * Allow showHelpPlus to have an extra/alternative question that is
    displayed.

  * All random seeds should be 42.

  * Reset kmeans tab on loading a project.

  * Add dozen more weather stations to the weatherAUS dataset.

  * Improve the logic for the display of the Report radio buttons on the
    Evaluate tab.

  * Spelling correction to a number of tooltips.

  * Default window height is 650, but not forced so that the window
    nicely fills a netbook screen if maximised.

  * Bump R dependency to 2.8.0 in line with update of the CITATION file.

rattle (2.5.21) stable; urgency=low

  * Re-enable gettext on MS/Windows, even though RGtk2 2.12.18 has not
    fixed the bindtextdomain problem with glade files and package supplied
    translations.

  * Change the tree plot to us "< =>" and ">= <" to clearly identify which
    branch the "=" results go. Could not figure out how to get expression
    to us a "ge" symbol.

  * Improve formatting of the PvO plots.

  * Use the pairs.panels function from the psych package for the default
    scatterplot on the Explore tab.

  * Add INSTALL file.

  * Ensure the right labels (Time/Risk rather than Class/Prob) displayed
    in filechooser when exporting a survival model.

  * Model tab renamed as Predictive.

  * Ensure boxplots have same "by ..." in the main title.

  * Update the weather dataset and include many more weather stations in
    the weatherAUS dataset.

  * Rtxt does no translations when running on MS/Windows (for now).
