Rolf,
I noticed this thread started by you as well as a few of the excellent
follow-ups. While it conclcuded, allow me a few quick comments:
- Some of us go through some effort to provide R on Ubuntu (and Debian) in a
reliable and reproducible manner. And it works and is used by many people.
- The basic r-base (and r-base-core etc) packages work in the distribution,
but may be older as the distribution is taken as snapshots in time. Hence
the Ubuntu mirror via CRAN. That way you get a choice between eg R 3.4.4
(not that old) and R 3.5.1. (brand new) in the current Ubuntu 18.04.
- The (short) instructions at CRAN work: add a repo, install from it.
Neither they nor the longer (more recent) blog post you found (which says
the same, with more pictures) suggest to link or move libraries around.
- We even have "proof" in the sense of fully automated build and use
systems. Docker is just one example. Eg this Dockerfile build the r-base
container available as rocker/r-base (as well as the official r-base)
https://github.com/rocker-org/rocker/blob/master/r-base/Dockerfile
and eg this one use it and builds on top to generated an RStudio container
https://github.com/rocker-org/rocker/blob/master/rstudio/testing/Dockerfile
Nowhere in either of these "recipes" are library files moved, renamed, or
otherwise altered.
- Nobody ever suggested for _any_ Linux distribution to mix its files below
/usr with your own compilation. There lies madness, and it may be the
root cause of the behaviour local to your machine. Don't do it.
- Please consider asking Debian and Ubuntu related questions on r-sig-debian.
Regards, Dirk
