     Methods for fitted ARMA model objects.

     ## S3 method for class 'arma':
     coef(object, ...)
     ## S3 method for class 'arma':
     residuals(object, ...)
     ## S3 method for class 'arma':
     fitted(object, ...)
     ## S3 method for class 'arma':
     print(x, digits = max(3, getOption("digits") - 3), ...)
     ## S3 method for class 'arma':
     plot(x, ask = interactive(), ...)

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

object, x: an object of class '"arma"'; usually, a result of a call to
          'arma'.

  digits: see 'printCoefmat'.

     ask: Should the 'plot' method work interactively?  See
          'interactive'.

     ...: further arguments passed to or from other methods.

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

     For 'coef', a numeric vector; for 'residuals' and 'fitted' a
     univariate time series; for 'plot' and 'print', the fitted ARMA
     model object.
