[R-sig-Debian] Where/how to set R_LIBS_SITE in R 4.2.0 for running R as R --vanilla to pick up "/usr/local/lib/R/site-library/"

[Sam H]

Dirk, thank you.

I do have the following lines in /usr/lib/R/etc/Renviron.site (see below):
  ## edd Apr 2003  Allow local install in /usr/local, also add a directory
for
  ##               Debian packaged CRAN packages, and finally the default
dir
  ## edd Jul 2007  Now use R_LIBS_SITE, not R_LIBS
  ## edd Mar 2022  Now in Renviron.site reflecting R_LIBS_SITE

R_LIBS_SITE="/usr/local/lib/R/site-library/:${R_LIBS_SITE}:/usr/lib/R/library'"

Unfortunately, somehow it doesn't work for me and I don't have a clue why:

## edd May 2019

## Debian (and its derivatives) impose a set of compiler flags to prevent
some known
## security issues with compiled code.  These flags then become defaults
for R as well
## (see eg /etc/R/Makeconf) but nevertheless confuse R as warnings get
triggers.  Users,
## on the other hand, are often stumped about these.  So with this variable
we declare
## these options as known for the local checks on the machine this file is
on.
##
## See Section 8 of the R Internals manual for many more options to
customize tests.
_R_CHECK_COMPILATION_FLAGS_KNOWN_='-Wformat -Werror=format-security
-Wdate-time'
