\title{Map between Kyoto Encyclopedia of Genes and Genomes (KEGG)
  pathway identifiers and Manufacturer Identifiers}
\description{
 hgu95av2PATH2PROBE is an R environment 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 \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:\\url{ftp://ftp.genome.ad.jp/pub/kegg/tarfiles/pathway.tar.gz}. Built: Release 41.1, February 1, 2007

  Entrez Gene:\\url{ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Thu Mar 15 20:55:24 2007

  Package built Thu Mar 15 21:19:18 2007

    # Remove pathway identifiers that do not map to any probe id
