[ESS] Upgraded to El Capitan (OS X 10.11) and ESS Cannot Find R

[Marc Schwartz]

Hi all,

Apologies for the delay in my follow up, I got pulled into a meeting.

The addition of exec-path-from-shell to my .emacs has resolved the problem.

Vincent, what are the modifications in your distribution to the above?

Stephen, to your first reply, using 'open -a Emacs' worked to run Emacs.app from within the OS X Terminal.

R did run in that setting, much as it did when I ran a shell in Emacs and started R from there. 

So there was some nuance in how Emacs was picking up the $PATH. This new addition of exec-path-from-shell will hopefully be more robust moving forward.

Unlike Vincent's experience, reinstalling R did not seem to reset things, despite doing a clean re-install. So some difference there.

Thanks to both of your for your rapid assist on this.

Regards,

Marc
