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

     Zero-pole-gain model of an ARMA filter.

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

     Zpg(zero, pole, gain)

     ## S3 method for class 'Arma':
     as.Zpg(x, ...)

     ## S3 method for class 'Ma':
     as.Zpg(x, ...)

     ## S3 method for class 'Zpg':
     as.Zpg(x, ...)

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

   zero : complex vector of the zeros of the model.

   pole : complex vector of the poles of the model.

   gain : gain of the model.

      x : model to be converted.

     ...: additional arguments (ignored). 

_D_e_t_a_i_l_s:

     'as.Zpg' converts from other forms, including 'Arma' and 'Ma'.

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

     An object of class "Zpg", containing the list elements: 

   zero : complex vector of the zeros of the model.

   pole : complex vector of the poles of the model.
