[R] Memory problems

[Prof Brian Ripley]

R does use virtual memory, and memory.size() (Windows only) is documented 
to report the usage, not change the limit.  Please read that help page 
more carefully.

If you are not already doing so, try arima0 rather than arima.

And do see the posting guide!
