_D_e_s_c_r_i_p_t_i_o_n:

     Plotting method for objects of class `"acf"'.

_U_s_a_g_e:

     plot(x, ci = 0.95, type = "h",
          xlab = "Lag", ylab = NULL, ylim = NULL, main = NULL,
          ci.col="blue", ci.type=c("white", "ma"), ...)

_A_r_g_u_m_e_n_t_s:

       x: an object of class `"acf"'.

      ci: coverage probability for confidence interval.  Plotting of
          the confidence interval is suppressed if `ci' is zero or
          negative.

    type: the type of plot to be drawn, default to histogram like
          vertical lines.

    xlab: the x label of the plot.

    ylab: the y label of the plot.

    ylim: numeric of length 2 giving the y limits for the plot.

    main: overall title for the plot.

  ci.col: colour to plot the confidence interval lines.

 ci.type: should the confidence limits assume a white noise input or
          for lag k an MA(k-1) input?

     ...: graphics parameters to be passed to the plotting routines.

_N_o_t_e:

     The confidence interval plotted in `plot.acf' is based on an
     uncorrelated series and should be treated with appropriate
     caution.  Using `ci.type = "ma"' may be less potentially
     misleading.

_S_e_e _A_l_s_o:
