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

     Produce a scatterplot showing raw data point location in retention
     time and m/z. This plot is more useful for centroided data than
     continuum data.

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

  object: the 'xcmsRaw' object

massrange: numeric vector of length >= 2 whose range will be used to
          select the masses to plot 

timerange: numeric vector of length >= 2 whose range will be used to
          select the retention times to plot 

scanrange: numeric vector of length >= 2 whose range will be used to
          select scans to plot 

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

     A matrix with the points plotted.
