Get it on Mac OS X
The easies way to get open source tools on Mac OS X is using Homebrew. But there is an additional dependency for R, which is not provided by Homebrew: XQuartz. Download and install the latest version, restart your Mac and then go on with Homebrew and R.
brew tap homebrew/science brew install r
This will also install required dependencies like Fortran.
Faster with OpenBLAS
OpenBLAS is library that should speed up calculations in R, but Homebrew does not install it by default. To install R with OpenBLAS bindings you can add the
brew install r --with-openblas
This will also install OpenBLAS itself through Homebrew.
Trouble with XQuartz?
I had some trouble with installing R the first time. The reason was an older version of XQuartz. I found the solution on Stackoverflow. A simple
brew doctor told me, I was running an outdated XQuartz version.
brew untap homebrew/science brew tap homebrew/science brew doctor
After installing the latest version and restarting my Mac, installing R worked fine.
Does it work now?
The quick check for success is starting R with the
R command (upper case matters). This should start R and you can type in some R code.
x <- 4 + 5 x
It should print 9 😉.
