[ESS] company-mode

[Vitalie Spinu]

You need to look into grouped company grouped backends.

Something along the following:

 (setq-local company-backends
    (append '((company-dabbrev-code company-R-args company-R-objects))
             company-backends))


Don't forget to

  (setq ess-use-company nil)

to avoid the "user-friendliness" of ESS.


BTW, my personal preference is to use M-/ as a complementary tool to auto
completion. I think squeezing all the tools into one key is rather inefficient.
