\title{Map between Kyoto Encyclopedia of Genes and Genomes (KEGG)
  pathway identifiers and TAIR Identifiers}
\description{
 org.At.tairPATH2TAIR is an R object that provides mappings between
 KEGG identifiers and TAIR 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 TAIR identifiers that are found in that
  particular pathway. An \code{NA} is reported for any KEGG identifier
  that cannot be mapped to any TAIR 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  
  With a date stamp from the source of: 2010-Sep7
