R on Binder: What happens if MRAN goes away?

See original GitHub issue

Apologies if this is a naive question, but here goes…

The documentation that describes configuring Binder to install R packages states that daily snapshots of CRAN that are hosted on MRAN are used. So what happens if MRAN disappears? More specifically, what dependencies are there on MRAN? Where are all the places it is used?

I want to setup my repo to trigger a packrat restore from a lock file instead of using MRAN. This provides better control over package versions (I’ve had problems, albeit rare, in the past when using checkpoint). Also, packrat works with packages installed from GitHub and BioConductor. I’ve already got this working locally, but not with Binder.

Thanks for the link! I created a new issue on the repo2docker repo to discuss the idea of using ncpus != 1.

With regards to “During the repo2docker build a lot of packages need to be compiled because there are no binaries for linux”:

Does repo2docker do this? https://www.jumpingrivers.com/blog/speeding-up-package-installation/
