[ESS] ess-tracebug

[Vitalie Spinu]

Hi Timothy, 

Incidentally, tracebug is on by default in devevlopment version and will
be probably on from ess 13.03. There are some glitches still to solve
though. 

Tracebug (and ess-developer) keys are now on dev-map C-c C-t (also in
12.09-2). You can still use ess-tracebug-prefix if you wish so.

I have just checked. It works fine for me. What is the string that is
printed for you? It should be something like:

+ Error in source(file = "/home/vitoshka/test.R") (from #1) : 
  /home/vitoshka/test.R:6:15: unexpected ','
5: {
6:     ret.x <- x,
                ^

Sometimes R does not report source locations. There is nothing that we
can do about it. There could also happen that R reports an error
location but tracebug doesn't' recognize it. Then it is a bug and you
should report definitely report it.

Sorry, it is just an old documentation. This function was removed because
it duplicated with the standard ess-load-file (C-c C-l). Just use C-c
C-l for sourcing files.
