_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)
      data(hgu95AchromNames)

_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 `multiget'. 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.

     `hgu95AchromNames' is a character vector with the chromosome names
     in the order, 1 through 22 then X then Y. This is useful for
     ordering the chromosomes in some plotting functions.

_S_o_u_r_c_e:

     The `AnnBuilder' package.

_E_x_a_m_p_l_e_s:

      data(hgu95Achrom)
      data(eset)
      multiget(geneNames(eset)[330:340], env=hgu95Achrom)
      data(hgu95AchromNames)
