ReactomePA is designed for reactome pathway based analysis (Yu and He 2016 ) . Reactome is an open-source, open access, manually curated and peer-reviewed pathway database.
Supported organisms
Currently ReactomePA supports several model organisms, including ‘celegans’, ‘fly’, ‘human’, ‘mouse’, ‘rat’, ‘yeast’ and ‘zebrafish’. The input gene ID should be Entrez gene ID. We recommend using clusterProfiler::bitr()
Reactome pathway over-representation analysis
Enrichment analysis is a widely used approach to identify biological themes. ReactomePA implemented enrichPathway() that uses hypergeometric model to assess whether the number of selected genes associated with a reactome pathway is larger than expected.

Pathway Visualization
ReactomePA implemented the viewPathway() to visualize selected reactome pathways. More general purpose visualization methods for ORA and GSEA results are provided in the enrichplot package and are documented in Chapter 13
