mqmplot.heatmap {qtl}R Documentation

Heatmap of a genome of MQM scan on multiple phenotypes

Description

Plotting routine to display a heatmap of results obtained from a multiple-QTL model on multiple phenotypes (the output of mqmscanall)

Usage

mqmplot.heatmap(cross, result, directed=TRUE, legend=FALSE, breaks =
c(-100,-10,-3,0,3,10,100), col =
c("darkblue","blue","lightblue","yellow","orange","red"), ...)

Arguments

cross An object of class cross. See read.cross for details.
result Result object from mqmscanall, the object needs to be of class mqmmulti
directed Take direction of QTLs into account (takes more time because of QTL direction calculations
legend If TRUE, add a legend to the plot
breaks Color break points for the LOD scores
col Colors used between breaks
... Additional arguments passed to the image function
