     KEGGPATHID2EXTID maps KEGG pathway ids to External ids. External
     ids include LocusLink ids for human, mouse, and rat and Open
     Reading Frame ids for yeast

_D_e_t_a_i_l_s:

     This is R environment object containing key and value pairs. Keys
     are KEGG pathway ids and values are External ids. KEGG pathway ids
     are the identifiers used by KEGG for various pathways. Values are
     vectors of length 1 or greater depending on whether a given KEGG
     pathway id can be mapped to only one or more external ids.  NAs
     are assigned to KEGG pathway ids that can not be mapped to any
     external id.

     This environment is intended to be used for the retrieval of all
     the LocusLink ids for human, mouse, and rat and the Open Reading
     Frame ids for yeast for a given pathway id. Mappings between KEGG
     pathway ids and pathway names can be obtained through another
     environment named PATHID2NAME.  

     Mappings were based on data provided by KEGG (<URL:
     ftp://ftp.genome.ad.jp/pub/kegg/pathways>)
