R and GNU tools via Homebrew

Introduction

I was in need of using stock Python (Homebrew provided version) from RStudio and I found that the user path is ignored by GUI applications. I discovered that because Python packages installed via pip were not recognised from RStudio. Here's my solution to make RStudio, and GUI apps in general, use stock Python.

Why should you do this?

To forget further complications such as downloading R installer and other tools when you want to update to a newer version. With a single brew upgrade you'll be ready.

What do you need to do this?

You'll need Homebrew and XCode installed. How to do that? check these links
