Dear R People: I found the following code on the Internet:
> x <- co2 > m <- HoltWinters(x, alpha=.1, beta=0, gamma=0) > p <- predict(m, n.ahead=240, prediction.interval=T) > plot(m, predicted.values=p) > and it works fine. My question: is there an equivalent for ARIMA objects, please? When I tried, I got the following: > x.arima <- arima(x,order=c(1,0,0)) > p1 <- predict(x.arima,n.ahead=6,prediction.interval=T) > plot(x.arima,predicted.values=p1) Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' is a list, but does not have components 'x' and 'y' > plot(x,predicted.values=p1) Warning messages: 1: In plot.window(xlim, ylim, log, ...) : "predicted.values" is not a graphical parameter 2: In title(main = main, xlab = xlab, ylab = ylab, ...) : "predicted.values" is not a graphical parameter 3: In axis(1, ...) : "predicted.values" is not a graphical parameter 4: In axis(2, ...) : "predicted.values" is not a graphical parameter 5: In box(...) : "predicted.values" is not a graphical parameter > Thanks in advance for any help!
