Set default CRAN mirror? about rocker

[cboettig]

Agreed, but how would you go about this?

In hadleyverse, I set CRAN as the default using a .Rprofile in root, so that at least I can use Rscript -e install_github.

In the RStudio image (and thus images depending on it), I can create the .Rprofile in the user's home directory as part of the script that runs on execution (via supervisord). I can't do it in the Dockerfile itself because we want to be able to specify a user variable at runtime, not hardwire it during build.

There are different users as @cboettig points out; RStudio runs as user 'rstudio'.

The sanest place would be /etc/R/Rprofile.site And we probably want to to set it in r-base rather than the later ones.

[cboettig]

@eddelbuettel I shoulda waited for you before committing, that's a much better solution.

You'd think I'd have caught on by now to use the global configs instead of adding crap to $HOME ...

Changes pushed to sandbox branch (As @eddelbuettel suggests, to avoid too many pointless builds on the Docker Hub we'll merge sandbox to master daily).

What about making sandbox the default branch for this repo? Then pull request would go there by default.

[cboettig]

Okay, this is now done in r-base.
