Assuming you are using Bash as your shell (I think it is the default in
OSX), to define R_HOME put 

export R_HOME="/Library/Frameworks/R.Framework/Resources"

Into ~/.bashrc and source it / restart the terminal session. If you're
using a different shell then Google for how to set environment variables.
