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

     Uses the pre-generated profile mode matrix to plot averaged or
     base peak extracted ion chromatograms over a specified mass range.

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

  object: the 'xcmsRaw' object

    base: logical, plot a base-peak chromatogram

   ident: logical, use mouse to identify and label peaks

fitgauss: logical, fit a gaussian to the largest peak

   vline: numeric vector with locations of vertical lines

     ...: arguments passed to 'profRange'

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

     If 'ident == TRUE', an integer vector with the indecies of the
     points that were identified. If 'fitgauss == TRUE', a 'nls' model
     with the fitted gaussian. Otherwise a two-column matrix with the
     plotted points.

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

     'xcmsRaw-class'
