\begin{Description}\relax
ygs98PATH2PROBE is an R object that provides mappings between
KEGG identifiers and manufacturer identifiers.
\end{Description}
\begin{Details}\relax
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 \code{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 \url{http://www.bioconductor.org}.

Graphic presentations of pathways are searchable at
\url{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 2007-Aug24

\begin{Examples}
\begin{ExampleCode}
    # 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]]
    }
