Rolf,
Sorry for only briefly chiming in, and late, but I don't usually follow r-help that much these days. I am writing this from an Ubuntu machine running R as well as RStudio from pre-made binary .deb packages. R comes via apt from CRAN (using Michael's binaries), RStudio from them via helper scripts in a package of mine: edd@rob:~$ dpkg -l | grep "r-base-core\|rstudio\|rstudio-server" | cut -c-79 ii r-base-core 4.1.0-1.2104.0 ii rstudio 2021-07.0.270 ii rstudio-server 2021-07.0.270 edd@rob:~$ Contrary to what you wrote, RStudio *will* use whichever binary it finds first in the path, just like any other Unix tool. So when I do $ rstudio I get R 4.1.0 from the binary above, but if I opt into my locally compiled R-devel via a standard PATH prefix then $ PATH=/usr/local/lib/R-devel/bin/:$PATH rstudio RStudio happily runs with R-devel. Next, "doc/". This has been in /usr/share/R for probably well over a decade on these Debian system; almost all other packages on Linux distros also split between binary ("architecture-specific") directories (such as lib/) and binary-independent ones (such as share/). And by the way, in R you can do call R.home() with an argument to see: > R.home("doc") [1] "/usr/share/R/doc" > R.home("library") [1] "/usr/lib/R/library" > Of course, you are free to use whichever R installation and configuration *you* mind most suitable. It is after all your machine. But quite a few of us are happy with these official binaries. Lastly, and I we may have mentioned this to you before, a dedicated mailing lists for 'R on Debian + Ubuntu' exists (in r-sig-debian at the usual ETH server) and you might have gotten useful answers sooner. Anyway, you are set now, so enjoy R!
