pvalHistogram: Histogram of the p values

Description

Creates an histogram of the pvalues. For multiple contrats, creates an histogram for every t.test pvalue (separate) or a single histogram for the F.test pvalue (nestedF). A uniform histogram will indicate no differential expression in the data set, whereas a right skewed histogram, will indicate some significant differential expression

Usage

pvalHistogram(fit2, DE, PVcut, DEmethod, MTestmethod, CM,verbose=FALSE)

Arguments

fit2

MArrayLM object

DE

TestResults object

PVcut

limit p value to declare significant features

DEmethod

method for decideTests, only 'separate' or 'nestedF' are implemented

MTestmethod

method for multiple test

CM

contrast matrix

verbose

logical, if TRUE prints out output
