Gets pathways from the MSigDB database in the format required by
clusterProfiler enrichment functions, such as
enricher and GSEA.
May be used as input to runEnrich. By default,
retrieves the C2 canonical pathways.
Usage
getMsigdbT2G(
species = "Homo sapiens",
category = "C2",
subcategory = NULL,
subcategory_to_remove = "CGP",
gene_id = "ensembl_gene"
)Arguments
- species
The species for which to obtain MSigDB pathways. See msigdbr for more details.
- category
The MSigDB category to retrieve pathways for. See msigdbr for more details.
- subcategory
The MSigDB subcategory to retrieve pathways for. See msigdbr for more details.
- subcategory_to_remove
If not NULL, this is a character string indicating a subcategory to be removed from the results of msigdbr.
- gene_id
The name to be given to the gene_id column of the resulting data.frame.
Value
Returns a data.frame, where the gs_name column indicates the name
of a pathway, and the gene_id column indicates genes that belong to
said pathway.
Examples
pathways <- getMsigdbT2G(
species = "Homo sapiens",
category = "C2",
subcategory_to_remove = "CGP",
gene_id = "ensembl_gene"
)
