Hi all: I met a question about plotting the predict values of time series. The data is treering which belongs to R. I want to predict the next 3 years(1980,1981,1982) result. pred<-predict(ar(treering),n.ahead=3) plot(treering) lines(pred$pred,col="red",lwd=3) I can only find a little bit red point at the end of the plot,but can't see it clearly. Maybe I should "subset" part of the original data via "window" function to make the predicted result visible: plot(window(treering,start = 1900)) lines(pred$pred,col="red",lwd=3) It's better than the first plot,but still can't see the predicted result clearly. Any suggestion from you are welcome. Many thanks. [[alternative HTML version deleted]]
