I would like to piggyback on this question:

1) Is there a way of getting completion with function names and

2) path completion is not working for me in my setup - might it be an interaction with org / ido
completion?

3) actually, object completion is also not working...

The inferior R process is running, and I get tooltips in the minibuffer.

Below please find the ESS section of my emacs.org file

Any suggestions welcome,

Rainer
