     hgu133aPATH2PROBE mappes KEGG pathway ids to probe ids

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

     This is an environment object with key and value pairs. Keys are
     KEGG pathway ids and values are the corresponding probe ids
     representing genes that are involved in the the pathways defined
     by the ids. Values are vectors of length 1 or greater depending on
     whether a given pathway id can be mapped to only one or more probe
     ids. Pathway ids can not be mapped to a probe identifier are
     assigned a value NA.

     Pathway name for a given pathway id can be obtained using the KEGG
     data package that can either be built using AnnBuilder or
     downloaded from Bioconductor <URL: http://www.bioconductor.org>.

     Mappings were based on data provided by:
