R_LIBS_USER

Version 3.4.1-2 of the r-base-core package reverts to the old behaviour.

Strictly personally speaking, I find that somewhat distateful -- but it is
the upstream default. I now set this in ~/.Renviron :

    ## Override possible ~/R/@p/@v directory
    R_LIBS_USER=""

and on the machines at work I may just do what I did before edit
/etc/R/Renviron or try the above via /etc/R/Renviron.site.

Thanks to everybody who chimed in, especially those who managed to stay calm.
