This is actually a fairly common question from R users at commercial institutions, where for various reasons upgrading to the latest release of R isn't always possible. This might be for regulatory reasons (only a certain distribution of R has been validated), because of IT policies, of because R is incorporated into a production application where the risk of breaking the application outweighs the potential benefits of an upgrade. This is actually one of the main reasons why the release cycle for REvolution R isn't as frequent as that for CRAN R. The beneficial side effect is that we can therefore provide support for older versions of R in our distributions. We support R 2.7.2 through our distribution of REvolution R Enterprise, for example.
