Re: Bug: ob-R.el breaks when :session is specified

[Christian Heinrich]

Hi Jeremie,

thank you for providing this example!

The ess that was found in the load path was years old and once updated, all 
issues were resolved. In
fact, my so-called minimum init still used (require 'package) and I didn't even 
think about ESS
causing this trouble.

It's now a bit clearer how to build a real minimum init - thank you!

This is hence resolved.

Best regards
Christian
