[R-sig-Debian] why is KEYWORDS.db not in '/usr/lib/R/doc/' but in '/usr/share/R/doc/'?

[Johan Andresen]

Hi r-sig-debian,

I feel lucky to have found out that `/doc/KEYWORDS.db` is in `/usr/share/R/`,
not in `usr/lib/R/` where rpy2 in python apparently looks for it when
trying to search help in R from the python environment. it returned this
error: `cannot open file '/usr/lib/R/doc/KEYWORDS.db': No such file or
directory`.

What to do now?
- is this a problem with rpy2 looking for `/doc/KEYWORDS.db` that should
not be in `usr/lib/R/`? -> *edit its script to point at the correct path?*
- or is it a problem with R for debian bullseye putting  `/doc/KEYWORDS.db`
in '/usr/share/R/doc/' where it should not be? -> why does it do that?
Should it be this way? Can I change it?

To be sure, searching help in RStudio and `help('help`) in R from the
terminal both worked. I installed both the way you suggest on lib.stat.cmu/R
/CRAN/bin/linux/debian/.
