If you are using the builds from r.research.att.com, you will need
RSwitch, which you can get from here:

http://r.research.att.com/#other

It's a small app which lets you select which version of R you want to
be "active" -- it simply shuffles the `Current` alias in
`/Library/Frameworks/R.framework/Versions` to point to the right place
(among other things, I guess).

I'm not sure what will happen if you want to run an R-2.15 GUI and an
R-2.16 GUI simultaneously -- I suspect this isn't easy to do, so ... I
mean, I'm not sure what would happen if RSwitch has 2.15 set as
current, and you launch R via the GUI. Then you tell RSwitch to set
R-2.16 as the current, then launch R form the terminal ... I suspect
this bad things will happen to your GUI session.

Anyway, that's one easy way (if a bit limited in flexibility) to do
what you want.

There are other ways to have R-2.15 and R-2.16 running side by side,
if you are comfortable compiling R-devel by source.

There's also lots of good info on this R-sig-mac thread:
