_D_e_s_c_r_i_p_t_i_o_n:

     These routines are primitives used with the `methods' package.
     They should not be used without it and do not need to be called
     directly in any case.

     `_s_t_a_n_d_a_r_d_G_e_n_e_r_i_c': dispatch the method defined for generic
          function named `f', using the actual arguments in the frame
          from which `standardGeneric' is called.

     `_o_b_j_W_i_t_h_C_l_a_s_s': return the result of setting the class of `object'
          to `value'.  Defined as a separate primitive function because
          R types cannot generally be changed in place.

     `_d_a_t_a_C_l_a_s_s': returns a single string for the class of `object'
          even in the case that the object has an old-style class
          attribute with multiple strings.

     `_t_o_p_i_c_N_a_m_e': the string used internally to find documenation of
          the given type and topic.  Called by the `?' operator and the
          special prompt functions in the methods package.
