Dirk,
Some lingering questions:
1. The packages that I have installed now through r2u have been sent to
"/usr/lib/R/site-library"
This is 4th on the list of .libPaths. Is there any reason for this? Somehow,
r2u does not like the presence of a user library in the home directory (even if
it is 1st on .libPaths)? Why?
2. bspm is now installed in
"/usr/local/lib/R/site-library"
this is 3rd on the list of .libPaths. Is it essential that it should be in one
of the sub-directories of local. See my next point also.
The bspm manual page says that any copy of the bspm package in a user library
must be uninstalled. It must be installed with administrative privileges, it
says. Why?
3.In a previous message, you had said that "bspm itself must be in /usr/local
for handshake to the python-apt interface". Would you like to explain what you
mean by this.
None of these questions are of an operational nature i.e. things that I have to
know to implement something. I am just being curious.
Thanks, Ravi

Installed a package. The process seemed to use r2u. Again, I followed Ivan and
restored the following lines in the script:
| echo "suppressMessages(bspm::enable())" >> ${RHOME}/etc/Rprofile.site
| echo "options(bspm.version.check=FALSE)" >> ${RHOME}/etc/Rprofile.site
We had told to comment those out for one step, and of course implied to turn
them back on by removing the comment. We may have been insufficiently clear.
Oh well. Now you know.

| sudo ./add_cranapt_noble.sh
Bad idea in the sense that a) you already ran it and b) these scripts are not
long / sophisticated enough to know to be robust to run N times in sequence.
The idea is to run them _precisely_ one time.

No 5k was a previous attempt. r2u was always north of 20k. On the '24.04 aka
noble' laptop here:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 24.10
Release: 24.10
Codename: oracular
$ apt-cache search r-cran-* | wc -l
23038
$ apt-cache search r-bioc-* | wc -l
492
$
Some come from the distro so it is a slight overcount. For the count of 'only
r2u' check the website, I post and update the numbers here.
| Thanks to you, Ivan. Thanks, Dirk, for your patient help.
Congratulations to you for persevering. I hope you enjoy r2u going forward.
Dirk

| | Try running bspm::enable() in a fresh R session. After that, do calls
| | to install.packages() in the same R session go through r2u? If yes,
| | feel free to restore the lines "suppressMessages(bspm::enable())" and
| | "options(bspm.version.check=FALSE)" in ${RHOME}/etc/Rprofile.site. If
| | no, maybe the resulting error messages provide more of a hint.
|
|
| That's actually a good debugging step:
| - check if you can use r2u without bspm, ie try to run
| sudo apt install r-cran-digest
| or any other package with more depenendies
| - if that works try to see why involving bspm does create an issue
|
| As Ivan noted, it matters to re-enable bspm in /etc/R/Rprofile.site
