An R Package for Exploring Molecular Signatures Database

The Molecular Signatures Database ('MSigDB') is one of the most widely used and comprehensive databases of gene sets for performing gene set enrichment analysis . The 'msig' package provides you with powerful, easy-to-use and flexible query functions for the 'MsigDB' database. There are 2 query modes in the 'msig' package: online query and local query. Both queries contain 2 steps: gene set name and gene. The online search is divided into 2 modes: registered search and non-registered browse. For registered search, email that you registered should be provided. Local queries can be made from local database, which can be updated by msig_update() function.
