The packages recommended by the R core team ( r-recommended) are updated in the Debian repositories on CRAN upon each new release of R (at least for the main architectures amd64 and i386). Therefore, updates of a subset of these R related packages are provided here for such Debian releases. Backports on CRANĪs R and related packages are currently not part of the official Debian backports repositories like buster-backports (please contact r-sig-debian if you would like to change this), the R versions in released or frozen Debian releases get out of date. This means that packages installed from within R take precedence over the ones installed via the Debian package management system if you happen to have two versions installed at the same time. On Debian and Ubuntu, R_LIBS_USER is set in /etc/R/Renviron to R_LIBS_USER=$

In order to find packages, R looks at the variables R_LIBS_USER and R_LIBS_SITE. If you would like to update R packages that have been installed via the Debian package management system which are installed somewhere under /usr/lib/, I would recommend to do this the Debian way using the source packages from Debian unstable.
