Attempt to convert the R image to Rocker

[abkfenris]

Attempting to convert the R image to Rocker, but it's kinda large.

Commented out install2.r packages are ones that we were installing from conda-forge and already are in the image unless noted otherwise.

I'm not sure that all of the github installed packages actually installed (multitasking rather than just observing the build logs). Maybe worth exploring some of these solutions: https://stackoverflow.com/questions/26244530/how-do-i-make-install-packages-return-an-error-if-an-r-package-cannot-be-install

Wow! Thanks! I'll give it a whirl later today

The underlying image is a lot of the size issue...

ghcr.io/rocker-org/binder          latest    0206f61770c7   8 weeks ago         7.43GB

We could adapt a pattern like this to install from github https://stackoverflow.com/questions/26244530/how-do-i-make-install-packages-return-an-error-if-an-r-package-cannot-be-install
