I usually call "sudo make install". Do I have to use "update-alternative --install R-2.7.1 R 2" if I want to have R-2.7.1 aqs the second priority installed? > > I have /opt in my PATH, thus I can call any R version explicitly by > R-x.y.z.

Thanks a lot - now I just have to know how I can do it under SuSE. I will keep this in mind and use it for my main cvomputer, which runs Xubuntu. Rainer > > Cheers, > > Berwin > -- Rainer M.
