My suggestion was to mimic *nix systems: put the executable binaries in the same place *by default* (e.g. /usr/bin/ or /usr/local/bin). Why isn't the default bin path for R under *nix something like /usr/bin/R-2.13.0/? If the users want to install multiple versions, they still have the choice to install them elsewhere. I'm not denying the possible necessity of having multiple versions in a system. In my opinion, the default values should be set according to probabilities: is it more likely for a user to use multiple versions or a single version of R? Of course, all of you are developers and the former probability might be higher, but I don't think many users will run the script A with R 2.12.1 and script B with R 2.13.0. The most typical situation I have seen is, (Windows) people install R and will forget to update it forever. I often have to urge our IT admin to update R in our department from a version released long long ago. You may argue my samples are not representative. Anyway, I can accept the default version string if nobody agrees with me.
I do use Emacs every day. It's nice, I totally agree.
