_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(hgu95Achroloc)

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

     These data sets provide environments with mappings from the
     Affymetrix identifiers to chromosomal location, in bases. The
     environments function like hashtables 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.

      mget(geneNames(sample.exprSet.1)[330:340], env=hgu95Achroloc, ifnotfound=NA)
