top.errorlod {qtl} | R Documentation |
Prints those genotypes with error LOD scores above a specified cutoff.
top.errorlod(cross, chr, cutoff=4, msg=TRUE)
cross |
An object of class cross . See
read.cross for details. |
chr |
A vector specifying for which chromosomes the error LOD scores should be inspected. |
cutoff |
Only those genotypes with error LOD scores above this cutoff will be listed. |
msg |
If TRUE, print a message if there are no apparent errors. |
A data.frame with 4 columns, whose rows correspond to the genotypes that are possibly in error. The four columns give the chromosome number, individual number, marker name, and error LOD score.
