Install R 3.x via homebrew

The R formula https://github.com/Homebrew/homebrew-core/commits/master/Formula/r.rb was upgraded from version 3.6.3 to 4.0 semi-recently. There are a few backward-incompatible changes in version 4, so I would like to have installations of both 3.x and 4.x on my system for testing.

Can that be achieved with homebrew? A simple attempt at brew install r@3.6 just gives me No available formula with the name "r@3.6".

(Aside: the upgrade from 3.6 to 4.0 happened rather sneakily on my system, I did a brew upgrade dvc and that upgraded a few dependencies [Installing dependencies for dvc: c-ares, protobuf, grpc, gcc, openblas, sqlite, python@3.8, numpy, zstd and apache-arrow] and then an avalanche of dependents:

==> Upgrading 42 dependents:

 python-yq 2.7.2 -> 2.10.1, qcachegrind 18.04.3_1 -> 19.08.3, r 3.6.3_1 -> 4.0.2_1,
 r 3.6.3_1 -> 4.0.2_1, shared-mime-info 1.15 -> 2.0, shared-mime-info 1.15 -> 2.0

which is is why I'm trying to get an installation of R 3.6 back.)

Note there seems to be no entry for the latest Mac big_sur in r's v3 formula, so @chenrui's method no longer works on new versions of Mac (it says Error: Failed to load formula: r: Invalid bottle tag symbol: Treating r as a cask.)

Solution: do the same as they suggest, but instead of the core repo, use the cask repo, and the revision you want to check out is 6d3bdc6 instead. Updated steps to follow:

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask # cask, not core
git reset --hard 6d3bdc6
git checkout -b r-3.6.3
HOMEBREW_NO_AUTO_UPDATE=1 brew reinstall homebrew/cask/r # Will install v3 from cask (which works on newer Macs), not formula (which is unsupported on newer Macs)
git checkout master

# Finally, since brew won't link this cask automatically:
ln -s /Library/Frameworks/R.framework/Resources/bin/R /usr/local/bin

Since R 3.6.3 is not actively maintained in the upstream, homebrew-core did not have a versioned formula for it. There is some hacky way of installing the most recent 3.6.3 version.

$ cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core # switch to your local homebrew-core folder

$ git reset --hard c3a244c627e # effective reset to the most recent r3.6.3 edition
Updating files: 100% (3680/3680), done.
HEAD is now at c3a244c627e r: update 3.6.3_2 bottle.

$ git checkout -b r-3.6.3 # this would prevent messing up your source tree
Switched to a new branch 'r-3.6.3'

$ brew reinstall r # this would reinstall 3.6.3_2

$ git checkout master # checkout back to source tree

==> Caveats
openblas is keg-only, which means it was not symlinked into /usr/local,
because macOS provides BLAS in Accelerate.framework.

For compilers to find openblas you may need to set:
  export LDFLAGS="-L/usr/local/opt/openblas/lib"
  export CPPFLAGS="-I/usr/local/opt/openblas/include"

For pkg-config to find openblas you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openblas/lib/pkgconfig"

Besides you can install thru the hacky way, I also made a legacy formula submission on this. https://github.com/Homebrew/homebrew-core/pull/58063
