     KEGGPATHID2EXTID maps KEGG pathway identifiers to Entrez Gene (for
     human, mouse, and rat) or Open Reading Frame (for yeast)
     identifiers

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

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

     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
