gseafun: Gene Set Enrichment Analysis (GSEA) Function

Description

This function performs gene set enrichment analysis using a gene list and a set of pathways.

Usage

gseafun(genelist, pathlist, nperm = 1000, weighted = 1)

Value

A data frame with enrichment scores (ES), p-values, and adjusted p-values.

Arguments

genelist

A named vector of gene expression values.

pathlist

A list of gene sets (pathways) to test for enrichment.

nperm

Number of permutations for calculating p-values (default is 1000).

weighted

Logical indicating whether to use weighted enrichment scores (default is TRUE).

Examples

data(path_list, package = "iPRISM")
data(genelist_imm, package = "iPRISM")
# \donttest{
res_gsea_imm <- gseafun(genelist = genelist_imm,
                        pathlist = path_list[1:2],
                        weighted = 1,
                        nperm = 1000)
print(res_gsea_imm)
# }
