_D_e_s_c_r_i_p_t_i_o_n:

     This method function extracts a formula from each of the 
     components of 'x', returning a list of formulas.

_U_s_a_g_e:

     ## S3 method for class 'reStruct':
     formula(x, asList, ...)

_A_r_g_u_m_e_n_t_s:

       x: an object inheriting from class 'reStruct', representing a
          random effects structure and consisting of a list of 'pdMat'
          objects.

  asList: logical.  Should the asList argument be applied to each of
          the components?

     ...: some methods for this generic require additional arguments. 
          None are used in this method.

_V_a_l_u_e:
