null_gsea: Calculate Null Distribution for GSEA

In vulcan: VirtUaL ChIP-Seq data Analysis using Networks

Description

This function generates a GSEA null distribution from

Usage

null_gsea(set, reflist, w = 1, np = 1000)

Arguments

set	A vector containing gene names.
reflist	A named vector containing the weights of the entire signature
w	exponent used to raise the supplied scores. Default is 1 (original scores unchanged)
np	Number of permutations (Default: 1000)

Value

A vector of null scores appropriate for the set/reflist combination provided

Examples

reflist<-setNames(-sort(rnorm(26)),LETTERS)
set<-c('A','B','D','F')
nulldist<-null_gsea(set,reflist)
nulldist[1:10]
