## Mappings between KEGG pathway identifiers and probe identifiers

### Description

KEGG (Kyoto Encyclopedia of Genes and Genomes) maintains pathway data for various organisms. Each pathway has a name, pathway id, and graphical presentation of the pathway. hgu133aPATH2PROBE maps KEGG pathway ids to probe identifiers representing genes whose products participate in the interactions of the pathway

### Details

Pathway name for a given pathway id can be obtained using the KEGG data package that can either be built using AnnBuilder or downloaded from Bioconductor http://www.bioconductor.org.

Graphic presentations of pathways are searchable at url{http://www.genome.ad.jp/kegg/pathway.html} using pathway ids as keys.

Mappings were based on data provided by:

KEGG:ftp://ftp.genome.ad.jp/pub/kegg/pathways. Built: Release 33.0 (January 2005)

LocusLink:ftp://ftp.ncbi.nih.gov/refseq/LocusLink/LL_tmpl.gz. Built: January 12, 2005

Package built Wed Jan 12 22:21:54 2005

### Examples

        # Convert the environment to a list
        xx <- as.list(hgu133aPATH2PROBE)
        # Remove pathway ids that do not map to any probe id
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # The probe ids for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
