PCA_gene_multiple: Do PCA for a single geneSet based on bootstraps by genes

In jmzeng1314/geneSet:

Description

It'll random choose the same number of gene with the size of this geneSet to extract the expression matrix and then do PCA for this small expression matrix .

Usage

PCA_gene_multiple(prefix = "test", exprSet, geneSet_list, n = 1000)

Arguments

prefix	The prefix for all of the output files.( we don't need it now actually,just placeholder)
exprSet	Matrix for microarray expression values,rownames must be genes, colnames must be samples
geneSet_list	A list which contains all of the vector for each geneSet.
n	Times for random permuted or bootstraps by genes,default:1000

Value

A numeric vector of P value for each PCA test about all of the geneSet .

Examples

PCA_gene_multiple(exprSet=exprSet, geneSet_list=geneSet_list)
