[ESS] looking for definitions of R functions

what are people using (if anything) to find declarations of R functions
within Emacs buffers?  e.g. when point is on the name of a function, you
hit a keybinding to look up the definiton of that function.

I just had some success with using dumb-jump.el
https://github.com/jacktasia/dumb-jump  -- it has a notion of a project
folder within which it will search for R function definitions
dynamically using a grep variant.  (It doesn't always work -- e.g. I
can't yet get it to fund hidden functions that begin with a period,
since I think it does not recognise the . as beginning of a word.)

But I'm just wondering if others had success with other packages?  We
mention TAGS files in our ESS documentation, and rtags.
