     hu6800GENENAME mappes probe ids to the names of genes
     corresponding to the probe ids. Gene names are the descriptions
     used for gene reports.

_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 names of genes. NAs are assigned to
     probe identifiers that can not be mapped to any gene name at this
     time.

     Gene names include both the official and preferred names for
     genes.

     Mappings were based on data provided by:
