I have been unable to get the homebrew version to install correctly.
On Mountain Lion the homebrew install also requires a few additional packages.
Install R with Homebrew
Update First run
brew tap homebrew/science to make the R package available /Update
If you run
brew install r when you do not have a fortran compiler you will see the following error:
This formula requires a fortran compiler, but we could not find one by looking at the FC environment variable or searching your PATH for
gfortran. Please take one of the following actions:
Decide to use the build of gfortran 4.2.x provided by Homebrew using
brew install gfortran
Choose another Fortran compiler by setting the FC environment variable: export FC=/path/to/some/fortran/compiler Using an alternative compiler may produce more efficient code, but we will not be able to provide support for build errors.
To save time just run :
brew update brew install gfortran r
Although I ran into some issues with linking libtiff and jpeg and had to run:
brew link -f libtiff jpeg brew install r
I still got checksum fails. Might have to wait for a brew update.
If you are running Mountain Lion then you will also run into this:
Unsatisfied dependency: XQuartz Please install the latest version of XQuartz: https://xquartz.macosforge.org Error: An unsatisfied requirement failed this build.
The easiest way to install R on OS X really does seem to be just run the package. 134MB install size.
