df.residual package:stats R Documentation _R_e_s_i_d_u_a_l _D_e_g_r_e_e_s-_o_f-_F_r_e_e_d_o_m _D_e_s_c_r_i_p_t_i_o_n: Returns the residual degrees-of-freedom extracted from a fitted model object. _U_s_a_g_e: df.residual(object, ...) _A_r_g_u_m_e_n_t_s: object: an object for which the degrees-of-freedom are desired. ...: additional optional arguments. _D_e_t_a_i_l_s: This is a generic function which can be used to extract residual degrees-of-freedom for fitted models. Consult the individual modeling functions for details on how to use this function. The default method just extracts the 'df.residual' component. _V_a_l_u_e: The value of the residual degrees-of-freedom extracted from the object 'x'. _S_e_e _A_l_s_o: 'deviance', 'glm', 'lm'.
