KEGGPATHID2EXTID {KEGG} | R Documentation |
KEGGPATHID2EXTID maps KEGG pathway ids to External ids. External ids include LocusLink ids for human, mouse, and rat and Open Reading Frame ids for yeast
This is R environment object containing key and value pairs. Keys are KEGG pathway ids and values are External ids. KEGG pathway ids are the identifiers used by KEGG for various pathways. Values are vectors of length 1 or greater depending on whether a given KEGG pathway id can be mapped to only one or more external ids. NAs are assigned to KEGG pathway ids that can not be mapped to any external id.
This environment is intended to be used for the retrieval of all the LocusLink ids for human, mouse, and rat and the Open Reading Frame ids for yeast for a given pathway id. Mappings between KEGG pathway ids and pathway names can be obtained through another environment named PATHID2NAME.
Mappings were based on data provided by KEGG (ftp://ftp.genome.ad.jp/pub/kegg/pathways)
