As far as I can tell from a quick look, "R Installation and Administration", as referred to by Wolfgang, just tells you how to install different versions in different places by using the configuration option --prefix (for Linux at least). This is some thing you always have to do, if you want to install several versions in parallel. However, once you have multiple versions installed, you need a mechanism to allow users to choose between them. This is where Environment Modules come in. At the simplest level, they just allow environment variables to be set and unset in an easy and consistent way. So it is not a question of "using the 'official' way of having co-existent R versions", but rather of installing various versions and then enabling people to choose easily between them. Or have I missed some intrinsic feature of R which will allow me to switch between installed versions without having to explicitly tweak environment variables?
