The primary use of \pkg{secrdesign} is to predict by Monte Carlo
simulation the precision or bias of density estimates from different
detector layouts, given pilot values for density and the detection
parameters lambda0/g0 and sigma.

The important functions in \pkg{secrdesign} are:
\tabular{ll}{
  \code{\link{make.scenarios}} \tab generate dataframe of parameter values etc. \cr
  \code{\link{scenariosFromStatistics}} \tab match specified n, r \cr
  \code{\link{run.scenarios}} \tab perform simulations, with or without model fitting \cr
  \code{\link{fit.models}} \tab fit SECR model(s) to rawdata output from \code{run.scenarios} \cr
  \code{\link{predict.fittedmodels}} \tab infer `real' parameter
  estimates from fitted models \cr
  \code{\link{select.stats}} \tab collect output for a particular
  parameter \cr
  \code{\link{summary.selectedstatistics}} \tab numerical summary of results \cr 
  \code{\link{plot.selectedstatistics}} \tab histogram or CI plot for
  each scenario \cr 
}

Documentation is provided in a vignette
\url{../doc/secrdesign-vignette.pdf}; an Appendix has code for various
examples that should help get you started. The help pages are also
available as \url{../doc/secrdesign-manual.pdf}.
