The msigdbr R package provides Molecular Signatures Database (MSigDB) gene sets typically used with the Gene Set Enrichment Analysis (GSEA) software:
The package can be installed from CRAN.
install.packages("msigdbr")
The package data can be accessed using the msigdbr()
function, which returns a data frame of gene sets and their member genes. For example, you can retrieve mouse genes from the C2 (curated) CGP (chemical and genetic perturbations) gene sets.
library(msigdbr)
genesets = msigdbr(species = "mouse", category = "C2", subcategory = "CGP")
