Dale,

Thanks for chiming in. Some very personal notes below:

I usually try my utmost not to.  Once packages are purge you cannot get them
back. I prefer to start an upgrade and back out if need be / if it would
remove package -- my go-to command is 'apt-get dist-upgrade' which allows that.

Yes though Michael has not yet announced these or declared them ready.

| sudo apt-get install r-base r-base-dev

Good point. And often forgotten.

Yep.

Actually, no!  Those are the ones from r-cran-* packages, and I would leave
those alone.

That is a basic Ubuntu / Debian question. Try googling for some tutorials on
'how to I add repositories to Ubuntu' (or Debian).

That you get a pre-built binary (with more bells and whistles) and don't need
to compile.

That is called 'package managment' (at the Debian / Ubuntu level).  Again,
tty some tutorials there.  This is orthogonal to R use.
