_D_e_s_c_r_i_p_t_i_o_n:

     Return full-resolution averaged data from multiple mass scans.

_A_r_g_u_m_e_n_t_s:

  object: the 'xcmsRaw' object

     ...: arguments passed to 'profRange' used to sepecify the spectral
          segments of interest for averaging 

_D_e_t_a_i_l_s:

     Based on the mass points from the spectra selected, a master
     unique list of masses is generated. Every spectra is interpolated
     at those masses and then averaged.

_V_a_l_u_e:

     A matrix with two columns: 

      mz: m/z values

intensity: intensity values
