[R] Retaining regularly used add-ons

[Liaw, Andy]

I'm a bit surprised that people haven't mentioned autoload().

The potential downside of loading to many packages or `large' packages
unnecessarily, I believe, is a bit slower response as R need to search
through a lot of names (in addition to taking up memory).

Cheers,
Andy
