[ESS] Go to function definition

[Vitalie Spinu]

This one is very handy, and work in all modes:

  https://github.com/vitoshka/imenu-anywhere

Otherwise there is always C-c C-e C-t (ess-build-tags-for-directory)
which works for R code and other languages as well. Then simply use
"M-.".

Unfortunately there is now internal "jump-to-source-location" function
in ESS. I had in plan to add one but never got down to it, partially
because the above two strategies work really well for me.
