I've now implemented and commited (to <ess>/lisp/essd-r.el )
the needed utilities:
There are now utility functions
and I have renamed Jim's (defun alt-ess-complete-object-name ..)
to new (defun ess-R-complete-object-name)
and changed it such that it works both for R < 2.7.0
and any other R with a correctly installed "rcompgen" package
(where R >= 2.5.0 comes bundled with "rcompgen" as a recommended
And yes, I have checked it in R-devel (2.7.0 to be) and an R
2.6.2 version and all seems to work nicely.

I think we should consider using it automatically instead of the
standard ESS completions when R >= 2.5.1 i.e. (with my new utility)
(if (ess-current-R-at-least '2.5.0) ...)
*HOWEVER* : In ESS we'd also want object completion in several
other places, notably for finding help pages, and
there, we'd still go through the non-R code.
