r-base 3.5.x is one of my requirements and it appears that 3.4 is the default R installed via repo2docker.
How can I change this? Is it possible to specify which version of R to use?
Changing the date to the latest mran snapshot appears to only affect packaged.
3.5 is available on MRAN.
Thanks in advance for your advice!
Unfortunately you can’t currently change the base version of R (easily).
There is an issue discussing adding this feature https://github.com/jupyter/repo2docker/issues/661 but so far no one has picked up the task. It would be a good feature to have though.
Thank you for your quick reply.
What would be the general process for changing r-base to a newer version provided that the container is up an running with 3.4?
Would one need to follow general upgrade instructions for Ubuntu from 3.4 to 3.5? (that potentially may be specified in the postBuild?
If anyone has done this your advice would be very much appreciated.
As mentioned in the issue you cited, R is currently at 3.6 so I agree with the comments that 3.5 is the current stabile version.
