Classes which already have methods for this function include 'pdMat', 'pdBlocked', and 'reStruct'. _U_s_a_g_e: matrix(object) <- value _A_r_g_u_m_e_n_t_s: object: any object to which 'as.matrix' can be applied. value: a matrix, or list of matrices, with the same dimensions as 'as.matrix(object)' with the new values to be assigned to the matrix associated with 'object'. _V_a_l_u_e: will depend on the method function; see the appropriate documentation. _A_u_t_h_o_r(_s): Jose Pinheiro Jose.Pinheiro@pharma.novartis.com and Douglas Bates bates@stat.wisc.edu _S_e_e _A_l_s_o: 'as.matrix' _E_x_a_m_p_l_e_s: ## see the method function documentation
