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

     For each element in the array of expression data, this applies the
     glog transform y -> glog (y-alpha, lambda). If alpha is a vector,
     it must have one entry per sample, and transeS will use the
     appropriate entry from the vector.

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

     transeS(eS, lambda, alpha)

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

      eS: An unprocessed expression set. 

  lambda: The parameter lambda to be used in the glog transform (Durbin
          and Rocke 2003). 

   alpha: The alpha parameter(s) for the glog transform. May be a
          single number used for all samples, or a vector with one
          entry per sample.

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

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

     Returns an expression set with the same vlist as eS, but the
     matrix is now glog-transformed. That matrix can be normalized with
     'norm' or 'lnorm'.

_N_o_t_e:

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