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

     Map a set of gene alias names to a set of gene symbols.

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

     alias2Symbol(alias, species = "Hs", expand.symbols = FALSE)

_A_r_g_u_m_e_n_t_s:

   alias: character vector of gene aliases

 species: character string specifying the species. Possible values are
          '"Dm"', '"Hs"', '"Mm"' or '"Rn"'.

expand.symbols: logical, should those elements of 'alias' which are
          already official symbols be expanded if they are aliases for
          other symbols.

_D_e_t_a_i_l_s:

     Aliases are mapped via NCBI Entrez Gene identity numbers using
     Bioconductor organism packages. Species are '"Dm"' for fly, '"Hs"'
     for human, '"Mm"' for mouse and '"Rn"' for rat. The user needs to
     have the appropriate Bioconductor organism package installed.

_V_a_l_u_e:

     A character vector of gene symbols. May be longer or shorter than
     the original vector.

_A_u_t_h_o_r(_s):

     Gordon Smyth and Yifang Hu

_S_e_e _A_l_s_o:

     This function is often used to assist gene set testing, see
     08.Tests.

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

     if(!require("org.Hs.eg.db")) alias2Symbol(c("PUMA","NOXA","BIM"))
