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

     Obtains an averaged calibration coefficient for an aligned
     calibration list. The obtained calibration coefficients can be
     used to transform the \Massvectorlist-class into the theortical
     coordinate system. It internally uses the function
     'getpepcalib-methods'

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

  object: Massvectorlist-class

    freq: The theoretical peptide frequency. default 1.000495

lengthmv: minimal length of peak-list (Massvector) to be used for
          calibration.

  mrange: see 'getpepcalib-methods'

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

     Returns an object of class 'Calibextstat-class'
