\title{Mappings between ORF identifiers and KEGG pathway identifiers}
\description{
  KEGG (Kyoto Encyclopedia of Genes and Genomes) maintains pathway data
  for various organisms. org.Pf.plasmoPATH maps ORF identifiers to the
  identifiers used by KEGG for pathways
}
\details{
  Each KEGG pathway has a name and identifier. 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 by 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

\examples{
    x <- org.Pf.plasmoPATH
    # Get the ORF identifiers that are mapped to a KEGG pathway ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the PATH for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }

    # For the reverse map:
    # Convert the object to a list
    xx <- as.list(org.Pf.plasmoPATH2ORF)
    # Remove pathway identifiers that do not map to any ORF id
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The ORF identifiers for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
