Map between probesets and KEGG pathway ID

Description

gahgu133aKEGGID is an R object that maps probe identifiers to the corresponding KEGG pathway ID.

Details

Each probeset maps to a vector containing the KEGG pathway ID. If the KEGG pathway ID is unknown, the vector will contain an NA.

Mappings were based on data provided by: Genecards ( http://www.genecards.org ) on 2009-mag06

Examples

        x <- gahgu133aKEGGID
        # Get the probe identifiers that are mapped to a KEGG pathway ID
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the KEGGID for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
