_D_e_s_c_r_i_p_t_i_o_n:

     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 environment 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 environment named PATHID2NAME. 

     Mappings were based on data provided by:
