[R] predict(arima)

[Remigijus Lapinskas]

Dear All,

R 1.9.1, Windows

When copying and pasting a few lines from the 'predict.Arima' help, I
get an error message:

> data(lh)
> predict(arima(lh, order = c(3,0,0)), n.ahead = 12)
Error in eval(expr, envir, enclos) : Object "xreg" not found

On the other hand, the following is OK:

> data(lh)
> predict(arima0(lh, order = c(3,0,0)), n.ahead = 12)
$pred
Time Series:
Start = 49 
End = 60

So, what is wrong with arima?

Thanking you in advance,
