Installing R with brew on Mac

I used to install R on Mac using brew.  However, recently, it seemed that the R package did not exist as a brew package anymore.  It turns out that I need to run the following command before maintaining the R installation with brew:

brew tap homebrew/science

After that R can be installed as before:

brew install R

Thanks for a comment on a blog post  for pointing this out.
