[R] install packages automatically

[john seers (IFR)]

Hi Vladimir

You may well be right and it is better, or at least better practice. But
I have a feeling I tried it and it was not as successful, but I cannot
remember why. Perhaps it was because when installing new packages they
were not installed in that (USER) directory?

I think using R_LIBS_USER is better.

>From ?.libPaths:

The library search path is initialized at startup from the environment
variable R_LIBS (which should be a semicolon-separated list of
directories at which R library trees are rooted) followed by those in
environment variable R_LIBS_USER.
