_D_e_s_c_r_i_p_t_i_o_n:

     If present in the calling sequence used to produce 'object', the

     ## S3 method for class 'gls':
     getData(object)

_A_r_g_u_m_e_n_t_s:

  object: an object inheriting from class 'gls', representing a
          generalized least squares fitted linear model.

_V_a_l_u_e:

     if a 'data' argument is present in the calling sequence that
     produced 'object', the corresponding data frame (with 'na.action'
     and 'subset' applied to it, if also present in the call that
     produced 'object') is returned; else, 'NULL' is returned.
