_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(hgu95All)

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

     These data sets provide environments with mappings from the
     Affymetrix identifiers to Entrez Gene identifiers. 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.

      data(sample.ExpressionSet)
      mget(featureNames(sample.ExpressionSet)[330:340], env=hgu95All, ifnotfound=NA)
