| If you want to update packages in R's default library in
| /usr/lib/R/library, you will need root permissions.
The way it is meant to work is that "you" (eric, the user) become a member of
the group owning that directory -- and I picked group 'staff' for that.
In the postinst (of the Debian / Ubuntu R packages), this directory is created
as
# edd 03 Apr 2003 cf Section 10.1.2 of Debian Policy
if [ ! -e /usr/local/lib/R ]; then
if mkdir /usr/local/lib/R 2>/dev/null; then
chown root:staff /usr/local/lib/R
chmod 2775 /usr/local/lib/R
fi
fi
if [ ! -e /usr/local/lib/R/site-library ]; then
if mkdir /usr/local/lib/R/site-library 2>/dev/null; then
chown root:staff /usr/local/lib/R/site-library
chmod 2775 /usr/local/lib/R/site-library
fi
fi
We could conceivably be fancier and create an R group on the system, but I
felt this is best left to local admins.
Alternatively, if you make that directory owned by 'you' then you don't need
root either.
You can check what group you are part of via 'id'. On my Ubuntu box, I am
member of a few groups:
edd@max:~$ id
uid=1000(edd) gid=1000(edd)
groups=1000(edd),4(adm),20(dialout),24(cdrom),27(sudo),44(video),46(plugdev),50(staff),107(lpadmin),115(admin),122(sambashare),124(libvirtd)
edd@max:~$
Hope this helps, Dirk
