     hgu133aPATH mappes probe ids to ids of KEGG pathways in which the
     genes represented by the probe ids are involved

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

     This is an environment object with key and value pairs. Keys are
     probe ids and values are the corresponding KEGG pathway ids.
     Values are vectors of length 1 or greater depending on whether  a
     given probe identifier can be associated with only one or more
     pathways. NA is assigned to probe ids that can not be associated
     with any pathway at this time.

     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:
