\begin{Description}\relax
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. hgu2beta7PATH2PROBE maps KEGG
pathway ids to probe identifiers representing genes whose products
participate in the interactions of the pathway
\end{Description}
\begin{Details}\relax
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 \url{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:\url{ftp://ftp.genome.ad.jp/pub/kegg/pathways}. Built: Release 33.0 (January 2005)

LocusLink:\url{ftp://ftp.ncbi.nih.gov/refseq/LocusLink/LL_tmpl.gz}. Built: February 16, 2005

Package built Wed Feb 16 23:32:20 2005

\begin{Examples}
\begin{ExampleCode}
    # Convert the environment to a list
    xx <- as.list(hgu2beta7PATH2PROBE)
    # 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]]
    }
