You can easily do so.
Just download the appropriate installers for each version and install
them:
2.8.x : http://cran.r-project.org/bin/macosx/R-2.8.0.dmg
2.7.x : http://cran.r-project.org/bin/macosx/old/R-2.7.2.dmg
FYI, they'll install in:
/Library/Frameworks/R.framework/Versions/2.*
You can switch between which version to run "at go time" as I
described in my previous email:
(i) either by using the RSwitch application; or
(ii) by renaming the R.app that's installed to R28.app, and R27.app
as appropriate.
Both RSwitch and the R guis can be downloaded from:

HTH,

ps - I'm not sure of (ii), since I haven't tested it for R27 vs R28
(only R in 68bit vs R 32bit, which works), though I believe it works.
I have tested and previously used (i).
