_D_e_s_c_r_i_p_t_i_o_n:

     Data, in the form of environments for the Affymetrix U95A chip.

_U_s_a_g_e:

     data(hgu95Achrom)

_F_o_r_m_a_t:

     This data set provides an environment (treat as a hashtable) with
     mappings from the Affymetrix identifiers to chromosome
     number/name. The environment functions like a hashtable and can be
     accessed using 'mget'. If the returned value is 'NA' then the
     current  mapping was unable to identify this. Mappings and data
     sources are constantly evolving so updating often is recommended.

_S_o_u_r_c_e:

     The 'AnnBuilder' package.

_E_x_a_m_p_l_e_s:

      data(hgu95Achrom)
      data(sample.exprSet.1)
      mget(geneNames(sample.exprSet.1)[330:340], env=hgu95Achrom, ifnotfound=NA)
