pLeft-methods: ~~ Methods for Function 'pLeft' ~~

In npGSEA: Permutation approximation methods for gene set enrichment analysis (non-permutation GSEA)

Description

This function returns the left-sided p-value for the corresponding GeneSet or a list of p-values for a GeneSetCollection. This method is only applicable for the normal and beta approximation methods.

Usage

pLeft(object)

Arguments

object

An object of type npGSEAResultNorm, npGSEAResultBeta, npGSEAResultNormCollection, or npGSEAResultBetaCollection

Methods

signature(object = "npGSEAResultNorm")

Returns a left-sided p-value for a npGSEAResultNorm object

signature(object = "npGSEAResultBeta")

Returns a left-sided p-value for a npGSEAResultBeta object

signature(object = "npGSEAResultNormCollection")

Returns a list of left-sided p-values for a npGSEAResultNormCollection objects (1 for each set)

signature(object = "npGSEAResultBetaCollection")

Returns a list of left-sided p-values for a npGSEAResultBetaCollection objects (1 for each set)

    yFactor <- as.factor( c(rep("treated", 5), rep("control", 5)) )
    xData <- matrix(data=rnorm(length(letters)*10) ,nrow=length(letters), ncol=10)
    rownames(xData) <- letters
    geneSetABC15 <- GeneSet(geneIds=letters[1:15], setName="setABC15")
    res <- npGSEA(x = xData, y = yFactor, set = geneSetABC15)
    pLeft (res)
