This function performs variable selection on gene expression matrices. It can, for instance, remove genes with low variation.

Description

This function performs variable selection on gene expression matrices. It can, for instance, remove genes with low variation.

Usage

doVariableSelection(exprMat, removeLowVaryingGenes = 0.2)

Arguments

exprMat	A matrix of gene expression levels. rownames() are genes, and colnames() are samples.
removeLowVaryingGenes	The proportion of low varying genes to be removed.The default is .2

Value

A vector of row/genes to keep.

Examples

try(doVariableSelection(exprMat, removeLowVaryingGenes = 0.2))
