_D_e_s_c_r_i_p_t_i_o_n:

     This function takes its argument as a intensity matrix of a set of
     spectra and plots the image as a heatmap.

_U_s_a_g_e:

     gelmap(Ma, cols = gray(seq(1, 0, by = -0.01)), at.mz = NULL, at.col = NULL, cexCol = 0.2 + 1/log10(nc))

_A_r_g_u_m_e_n_t_s:

      Ma: a matrix of intensities; spectra are arranged column-wise.

    cols: a vector of color to represent continuum of intensities.

   at.mz: a vector of m/z values where labels are desired.

  at.col: a vector of sample indices, useful to label particular
          samples. If NULL, samples will be labelled from down up by
          1:ncol(Ma). 

  cexCol: text size of the sample labels.
