_D_e_s_c_r_i_p_t_i_o_n:

     gahgu95bCHR is an R environment that provides mappings between a
     custom probeset identifier and the chromosome that contains the
     gene of interest.

_D_e_t_a_i_l_s:

     Each identifier maps to a chromosome. If the chromosomal location
     is unknown, the vector will contain an 'NA'.

     Mappings were based on data provided by:
