Arguments

geneList

A numeric vector with gene as names.

keytype

"Entrez" or "Symbol".

type

Molecular signatures for testing, available datasets include Pathway (KEGG, REACTOME, C2_CP), GO (GOBP, GOCC, GOMF), MSIGDB (C1, C2 (C2_CP (C2_CP_PID, C2_CP_BIOCARTA), C2_CGP), C3 (C3_MIR, C3_TFT), C4, C6, C7, HALLMARK) and Complex (CORUM). Any combination of them are also accessible (e.g. 'GOBP+GOMF+KEGG+REACTOME').

method

One of "ORT"(Over-Representing Test), "GSEA"(Gene Set Enrichment Analysis), and "HGT"(HyperGemetric test).

organism

'hsa' or 'mmu'.

pvalueCutoff

FDR cutoff.

limit

A two-length vector (default: c(2, 200)), specifying the minimal and maximal size of gene sets for enrichent analysis.

universe

A character vector, specifying the backgound genelist, default is whole genome.

filter

Boolean, specifying whether filter out redundancies from the enrichment results.

gmtpath

The path to customized gmt file.

verbose

Boolean

Value

enrichRes is an enrichResult instance.
