gelDiff: Laplace p-value matrix

In aarkatkar/gelClust: Clustering and pathway analysis using exponential distributions

Laplace p-value matrix

Description

Obtain a p-value matrix of the laplace distributed difference between two different outputs of the gelMatrix function. If twoTailed == FALSE, the p-value describes correlations that are more significant in the first gelMatrix than the second.

Usage

gelDiff(gm1, gm2, twoTailed = FALSE, unifOut = FALSE)

Arguments

gm1	The first gelMatrix
gm2	The second gelMatrix
twoTailed	Whether to make the resulting p-values two-tailed
unifOut	Whether to force the output to the uniform distribution

Value

A p-value matrix of the same dimensions as the each input gelMatrix. This matrix may be used in place of gelMatrix for any function in this package.
