[ESS] Auto-completion with Company

[Mathieu Basille]

Hi,

After some time using auto-complete in Emacs, I'm now trying to modernize
my configuration and switch to Company. I understand that Company is fully
integrated to ESS now, and works out of the box, however, I get a weird
error message when I try to "use" it.

Here are the steps that I followed:

* Install Emacs 25.1, ESS 16.10 and Company (elpa-company) 0.8.12 from
Debian repository (I am running Testing/Stretch).

* Prepare a minimal .emacs.d/init.el with only this:

(add-hook 'after-init-hook 'global-company-mode)

(require 'ess-site)

* Open any file with Emacs: auto-completion works as expected, for instance
if I type the same word twice, auto-completion kicks in for the second type.

* Open a .R script in Emacs, open R (M-x R), and try auto-completion on a
function (for instance, typing "hi" to get hist/history/... Auto-completion
does not work, and I get a message in the echo area instead:

Company: An error occurred in auto-begin
Company: Back-end (company-R-args company-R-objects :separate) error
"Symbol’s function definition is void: :separate" with args (ignore-case)

I couldn't find much help in the doc, or other on-line resources.

Any help would be greatly appreciated! Thanks in advance,
Mathieu Basille.
