Hi Aleblanc,

Sorry for late reply, I was away for a little and didn't check my mails.

You should see a highlighted line and a small triangle in the fringe for the
currently debugged code in the source buffer.

This would work only if your previously soused the file explicitly with source()
 command or with C-c C-b or M-c s (the latest is defined in ess-tracebug).

 Ess-tracebug recognizes automatically source references of the form
 pbm_funcs.R#336 and similar.
 If you don't see this in the R process output there is no way to recognize
 where to jump, though you can still jump with M-c n n n...

 Let me know if you still have trouble,
