     KEGGEXTID2PATHID maps External ids to KEGG pathway id. 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 an environment object containing key and value pairs. Keys
     are External ids and values are KEGG pathway ids. Values are
     vectors of length 1 or greater depending on whether a given
     external id can be mapped to only one or more KEGG pathway ids.
     NAs are assigned to external ids that can not be mapped to any
     pathway id.

     KEGG pathway ids are the identifiers used by KEGG for various
     pathways. 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>)
