_D_e_s_c_r_i_p_t_i_o_n:

     Calculate and plot roots of a model.

_U_s_a_g_e:

         addPlotRoots(v, pch='*', fuzz=0)

_A_r_g_u_m_e_n_t_s:

       v: An object containing a TSmodel.

     pch: Character to use for plotting.

    fuzz: If non-zero then roots within fuzz distance are considered
          equal.

_V_a_l_u_e:

     The eigenvalues of the state transition matrix or the inverse of
     the roots of the determinant of the AR polynomial are returned
     invisibly.

     if(is.R()) data("eg1.DSE.data.diff", package="dse1")
     model <- estVARXls(eg1.DSE.data.diff)
     plot(roots(model))
