Installing different versions of R simultaneously on Linux
This is really an R-devel question.

Hi I want to install some versions of R simultaneously from source on a computer (running Linux). Some programs have an option to specify a suffix for the executable (eg R would become R-2.7.2 when the suffix is specified as "-2.7.2"). I did not find this option for R - did I overlook it? If it is not, how is it possible to have several versions of R on one computer, or is the only way to compile them and then call R in the directory of the version where it was compiled (~/R-2.7.2/bin/R)? If this is the case, would it be possible to add this o[ptiuon to specify the suffix for the executables?
'R' is not an executable, but a shell script. You can use 'prefix' to install R anywhere, or other variables for more precise control (see the R-admin manual). For example, we use rhome to have R 2.8.x under /usr/local/lib64/R-2.8 etc. And you can rename $prefix/bin/R to, say, R-2.7.2, or link R_HOME/bin/R to anywhere in yout path, under any name you choose.
