_D_e_s_c_r_i_p_t_i_o_n:

     Produce scatter plots of M values vs A values of the samples.

     _Usage_

     ' mvaplot(x, transfo = log2, method  = "median", names =
     "namepart", ylim = c(-6,6), ...) '

_A_r_g_u_m_e_n_t_s:

       x: object of class 'ExprTreeSet'.

 transfo: a valid function to transform the data, usually "log2", or
          "0".

  method: method to compute M, "mean" or "median".

   names: optional vector of sample names.

    ylim: range for the plotted M values.

     ...: optional arguments to be passed to 'plot'.

_D_e_t_a_i_l_s:

     Produces mvaplots for slot 'data' for an object of class
     'ExprTreeSet'.

     For 'names=NULL' full column names of slot 'data' will be
     displayed while for  'names="namepart"' column names will be
     displayed without name extension. If 'names' is a vector of column
     names, only these columns will displayed as mvaplot.
