[R] Tool for update

[Prof Brian Ripley]

You might want to look at the new tools in 2.1.0alpha for this sort of 
thing.  In particular, packageStatus() is now built on top of the new 
tools that it may be cleaner to call directly.

For what I understand you run this every time you use R on a Tuesday, 
which is not what I would want.
