I\'m trying to install R using Homebrew. I ran these commands which are recommended elsewhere on SO:
brew tap homebrew/science brew install R
If you meant "r" specifically: It was migrated from homebrew/science to homebrew/core.
For r 3.4.3 Mac High Sierra:
r 3.4.3
High Sierra
brew tap homebrew/core brew install Caskroom/cask/xquartz brew install r
