Dear all, The backports of R 3.4.2 (providing r-api-3.4) to Debian stretch and Debian jessie have just hit CRAN. Should you still have R packages (e.g. r-cran-*) from regular Debian jessie/stretch on your system they would be removed if you install such a backport. For some more information, see https://cran.r-project.org/bin/linux/debian/ as usual. Please let me know in case the backport does not work as it should. Cheers, Johannes
