     hgu95av2SYMBOL mappes probe identifiers to the symbols used to
     report genes represented by the probe ids

_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 gene symbols. Values
     are vectors of length 1. NA is assigned to probe ids that can not
     be mapped to any gene symbol. 

     Mappings were based on data provided by:
