## Map between Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway identifiers and Manufacturer Identifiers

### Description

ygs98PATH2PROBE is an R object that provides mappings between KEGG identifiers and manufacturer identifiers.

### Details

Each KEGG identifier is mapped to a named vector of manufacturer identifiers. The name represents the KEGG identifier and the vector contains all manufacturer identifiers that are found in that particular pathway. An `NA` is reported for any KEGG identifier that cannot be mapped to any manufacturer identifiers.

Pathway name for a given pathway identifier 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 http://www.genome.ad.jp/kegg/pathway.html using pathway identifiers as keys.

Mappings were based on data provided by: KEGG GENOME ( ftp://ftp.genome.jp/pub/kegg/genomes ) on 2008-Apr1

### Examples

        # Convert the object to a list
        xx <- as.list(ygs98PATH2PROBE)
        # Remove pathway identifiers that do not map to any probe id
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # The probe identifiers for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
