I\'ve installed python 2.7.8 alongside the 2.7.5 which comes with OSX 10.9.4.

Now how can I point rPython to python 2.7.8?

I setup the following commands in RStudio, hope these help.

> system("python --version")
Python 2.7.10

> Sys.setenv(PATH = paste("/usr/local/bin", Sys.getenv("PATH"),sep=":"))

> system("python --version")
Python 2.7.11
