doVolcanoplot {StabPerf}R Documentation

Draws a volcano plot for expression values (fold changes vs. p-values)

Description

Similar to the volcanoplot function (See volcanoplot) in package limma, but works with plain vanilla data and requires not special MArrayLM objects.

Usage

doVolcanoplot(fc=NULL, p=NULL, main=NULL)

Arguments

fc numeric. Fold changes.
p numeric. p-values.
main See plot

Details

To make the graphic easier to digest the p-values are displayed as -log10(p-values).
