SIN (version 0.4)

plotUGpvalues: Plot simultaneous p-values for undirected graphs

Description

This function plots the simultaneous p-values for SIN model selection for undirected graphs.

Usage

plotUGpvalues(pvals, legend=TRUE, legendpos=NULL)

Arguments

pvals

a matrix of p-values.

legend

a Boolean.

legendpos

a numerical vector of length 2.

Value

• A plot illustrating the simultaneous p-values. If legend==TRUE, then a legend giving information on the variable labelling is drawn. Optionally, the position of the legend can be specified by legendpos.
