     KEGGEXTID2PATHID maps Entrez Gene (for human, mouse, and rat) and
     Open Reading Frame (for yeast) identifiers to KEGG pathway
     identifiers.

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

     This is an R object containing key and value pairs. Keys are
     Entrez Gene identifiers for human, mouse, and rat and Open Reading
     Frame (ORF) identifiers for yeast and values are the corresponding
     KEGG pathway identifiers. Values are vectors of length 1 or
     greater depending on whether a given external identifier can be
     mapped to only one or more KEGG pathway identifiers.  NAs are
     assigned to Entrez Gene or ORF identifiers that can not be mapped
     to any pathway identifier.

     KEGG pathway identifiers are the identifiers used by KEGG for
     various pathways.

     Mappings between KEGG pathway identifiers and pathway names can be
     obtained through another annotation data object named
     KEGGPATHID2NAME. 

     Mappings were based on data provided by: KEGG GENOME (
     ftp://ftp.genome.jp/pub/kegg/genomes ) on 2008-Apr1
