[R] Arima forecasting

[Stephan Kolassa]

Hi Matteo,

just use forecast.Arima() with h=2 to get forecasts up to 2 steps ahead. 
R will automatically use forecast.Arima() if you call forecast() with an 
Arima object.

library(forecast)
model <- auto.arima(AirPassengers)
forecast(model,h=2)

HTH,
Stephan
