msigdbr R package provides Molecular Signatures Database (MSigDB) gene sets typically used with the Gene Set Enrichment Analysis (GSEA) software:
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.
genesets = msigdbr(species = "Mus musculus", category = "C2", subcategory = "CGP")
