To the best of my knowledge, nobody ever claimed it was. I have seen people
state that they use the packages [ that are built for Debian in a Debian
chroot ] on Ubuntu; I myself have not attempted that and am unlikely to do it.

Mixing the two can be confusing, but given how the library path is set up _in
the packaged version_ (as opposed to builds from raw R upstream sources) you
get a clean split of

    /usr/local/lib/R/site-library/        used by install.packages()

    /usr/lib/R/site-library		  used by r-cran-* packages
    /usr/lib/R/library			  used by 'core' r-cran-* packages

so apt-get will never install where install.packages() installs and vice versa.

One day we hope to have cran2deb for Ubuntu but the ETA is unknown.
