Looking forward to that! But it is not working at present.
The link above points to the development version ess-13 which
I downloaded using svn export (I got version 13.03, running
on a Mac with emacs 24.3).
Completion of object names works in the inferior ESS buffer
but not yet in an ESS buffer ( .R file).
