KEGGEXTID2PATHID {KEGG}R Documentation

An annotation data file for EXTID2PATHID in the KEGG package

Description

KEGGEXTID2PATHID maps External ids to KEGG pathway id. External ids include LocusLink ids for human, mouse, and rat and Open Reading Frame ids for yeast

Details

This is an environment object containing key and value pairs. Keys are External ids and values are KEGG pathway ids. Values are vectors of length 1 or greater depending on whether a given external id can be mapped to only one or more KEGG pathway ids. NAs are assigned to external ids that can not be mapped to any pathway id.

KEGG pathway ids are the identifiers used by KEGG for various pathways. 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)

Source data built: Release 29.0 (January 2004).

Examples

        require("annotate") || stop("annotate unavailable")
        xx <- as.list(KEGGEXTID2PATHID)
        if(length(xx) > 0){
                # Get the value of the first key
                xx[[1]]
                # Get the values for a few keys
                if(length(xx) >= 3){
                        xx[1:3]
                }
        }
