plotDAGpvalues {SIN}R Documentation

Plot simultaneous p-values for acyclic directed graphs

Description

This function plots the simultaneous p-values for SIN model selection for acyclic directed graphs (DAGs).

Usage

plotDAGpvalues(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.
