[GRASS-user] Creating an R Container with GRASS support

[Mehrdad Varedi]

Hi Markus,
I used the Dockerfile you shared and began from the r-base instead of
ubuntu, it worked very well. Only, the image is a little big which is more
a docker issue.
If you have any recommendations, I would appreciate it, although this is
not a GRASS question.

Thanks and Kind regards,

Mehrdad
