mqmplot.multitrait {qtl}R Documentation

Plot the results from a genomescan using a multiple-QTL model on multiple phenotypes

Description

Plotting routine to display the results from a multiple-QTL model on multiple phenotypes. It supports four different visualizations: a contourmap, heatmap, 3D graph or a multiple QTL plot created by using plot.scanone on the mqmmulti object

Usage

mqmplot.multitrait(result, type=c("lines","image","contour","3Dplot"),
                   group=NULL, meanprofile=c("none","mean","median"),
                   theta=30, phi=15, ...)

Arguments

result

Result object from mqmscanall

type

Selection of the plot method to visualize the data: "lines" (defaut plotting option), "image", "contour" and "3Dplot"

group

A numeric vector indicating which traits to plot. NULL means no grouping

meanprofile

Plot a mean/median profile from the group selected

theta

Horizontal axis rotation in a 3D plot

phi

Vertical axis rotation in a 3D plot

...

Additional arguments passed to plot.
