Add rig repos ...

[gaborcsardi]

To query and configure repositories. In particular have a config option (do we need rig config?) to whether we should set the repos in RStudio (and Positron) or not.

Instead of rig config we can also write the config into the profile.

We should be able to configure different repos for different R versions:

• R-devel does not have PPM binaries.
• Older macOS and Windows binaries are on cran-archive.

By default all these should be configured automatically. (Observing the --without-cran-mirror and --without ppm options of git add.)

I've encountered an issue that this may solve. I'm using rig with Pop OS 22.04 and I encounter this error when running rig add 4.4.1:

[ERROR] Failed to resolve R version: Cannot download JSON: HTTP status client error (404 Not Found) for url (https://api.r-hub.io/rversions/resolve/4.4.1/linux-pop-22.04/x86_64)

Perhaps adding an option to the config allowing the user to manually specify their linux installation would solve this problem.

You probably need to set RIG_PLATFORM, see https://github.com/r-lib/rig/pull/241/files#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5R200

Ahhh, that is exactly what I needed, thank you!

I think that the source ~/.profile needs to be run without sudo:

sudo: source: command not found
