Mention r-lib/rig

Thanks for this book, all the new additions are great!

A small suggestion: It might be nice to mention rig https://github.com/r-lib/rig in the system setup chapter as a way to manage R installations and use separate libraries for package development.

It looks like this will not make it into the printed version, because rig just hasn't been around long enough for us to have lots to say about it, have lots of experience with a broad user base, etc. However, I'm very keen on rig and suspect it will see increasing usage. So once the publication process specific to printing the second edition dies down, I'd definitely like to add rig to the online version going forward.

Awesome! rig has solved some friction points in my work/setup so I'm hoping more people start using it.

I don't know how relevant it might be for this book, but rig plus pak makes your How to transfer your library when updating R guide in the Maintaining R chapter of rstats.wtf a lot easier---I wrote about it here. Maybe if the system setup chapter was expanded to include a Maintaining R section you could work in a more substantive discussion of rig.
