[R] summary on predict with arima0

[Erin Hodgess]

Here is the summary on predict when
using an arima0 object:

The arima0 object must be based on a time series vector.

That is;
x <- ts(xm1, frequency=12, start=c(1975,1))
x.ar <- arima0(x,order=c(1,1,1))
predict(x.ar,n.ahead=3)

Thanks so much to Prof. Brian Ripley and David Brahm and other!

Sincerely,
Erin Hodgess
