Explicitly installed R packages are here: https://github.com/sagemath/sagecell/blob/master/contrib/vm/container_manager.py#L255
If there is something else that you need - test is on sagecell.sagemath.org and let me know if it does not work. In general, anything that can be installed in a standard way can be added. While explicit versions and custom commands tend to be too fragile to maintain.
