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

Description Usage Arguments Value Examples

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

1
PCA_gene_single(prefix = "test", exprSet, this_geneSet, 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

this_geneSet

A vector which contains all of the genes in this geneSet.

n

Times for random permuted or bootstraps by genes,default:1000

Value

The p vaule for this PCA test

Examples

1
PCA_gene_single(exprSet=exprSet,this_geneSet=this_geneSet)
