[R] arima forecast function

[Gabor Grothendieck]

forecast must be quoted:

install.packages("forecast")

and in this case its actually part of the forecasting bundle so we
could also do this:

install.packages("forecasting")

Look at ?install.packages and note the way it works for different values of
the dependencies argument.
