Hi Vitalie,

sorry for not coming back to you earlier.

Makes sense. So here we go:

I have written a small test package and put it on dropbox 

https://www.dropbox.com/s/qnoo78h9phpapjo/testTraceback_0.0-1.tar.gz

If you install the package, load it and call the function testprg, I get
the following:

,----
| > install.packages("packages/testTraceback_0.0-1.tar.gz", repos=NULL, type="source")
| Installing package into '/Users/rainerkrug/Documents/Projects/AlienManagementDrakensberg/sim/library'
| (as 'lib' is unspecified)
| * installing *source* package 'testTraceback' ...
| ** R

| ** help

| *** installing help indices
| ** building package indices
| ** testing if installed package can be loaded
| * DONE (testTraceback)
| > library(testTraceback)
| > testprog(3)
| Error in testprog(3) : object 'hallo' not found
| >
`----

No traceback is available - ess debug minor mode is enabled

When I use the devtools package and load_all() to load the directory, I
get the following:

,----
| > Library("devtools")
| > load_all("packages/testTraceback/")
| Loading testTraceback
| > testprog(2)
| Error in testprog(2) (from <text>#3) : object 'hallo' not found
| >
`----

and no further information.

When I source the file, I get the full traceback:

,----
| > source("packages/testTraceback/R/testprog.R")
| > testprog(3)
| Error in testprog(3) (from testprog.R#3) : object 'hallo' not found
| >  
`----

I am using the official installation of R (3.0.1) for Mac, GNU emacs and
ESS from git (ess-version : 13.05-1 [<unknown>]).

Any suggestions on why the information is not comming through when using
load_all()? It was working under Linux, and I did not change my emacs.el
file.

Thanks,

Rainer
