R 3.4.0 and devel tags are now available in the Rocker versioned stack, and latest has been updated to 3.4.0.

This means you can now run something like:

docker run -d -p 8787:8787 rocker/tidyverse:devel

to test out a recent version1 of R devel in RStudio with the tidyverse packages already installed. Note that the packages are not themselves devel versions (e.g. from GitHub) but are instead the latest versions from CRAN, just as in the latest tag. Only the base R system is on devel. This can be handy for testing packages prior to CRAN release.

  1. devel tags should now be triggered nightly by a tag-specific curl POST from cron for each image. Since this requires we remove the simple ‘repository linking’ in Docker hub to avoid the whole stack rebuilding all tags, this requires a second set of cron calls to see that the rest of the stack is also updated regularly. These calls are currently scheduled to rebuild all tags on the first day of the month. A bit more engineering, but at least the crontab should not require regular updating with new releases, since devel tag is always devel. We’ll see how well this part works.
