My edtdbg debugging tool is now on CRAN, at
http://cran.r-project.org/web/packages/edtdbg/index.html
I've added a few new commands since the last time I announced the
package here. I'll enclose command list at the end of this message.
Currently the package is implemented for Vim. I have a volunteer to
adapt it to Emacs, so I'm hopeful it will be usable for Emacs fans
later.
I'm still looking for time to prepare my Rdsm parallel R package for
submission to CRAN. The code is all ready, though, so if anyone wishes
to obtain it, just let me know.

Here are the edtdbg commands, typed within the editor:
* ,dbg
Start edtdbg.
* ,dbgu
Exit ‘edtdbg’.
* ,src
Tell R to source the file you have in your current Vim
buffer.
* [
If you are in the browser in your R window, hitting the
left-bracket key runs the browser's n command. Your Vim
cursor will then automatically move to the new line, i.e. to
the one that the browser will now be on.
* ]
Same as [, but runs the c command instead of n.
* ,dsp
This toggles display. When display is on, the values of the
current function's arguments and local variables will appear
in the R window after each debug step.
* ,mom
This displays the arguments and local variables in the parent
function, i.e. the next-higher frame in the call stack. The
action occurs once per time you invoke the command.
* ,glb
This displays all global variables. The action occurs once
per time you invoke the command.
* ,br
This sets a breakpoint at the line after the current cursor
line of the editor. This is done by inserting a call to
browser() and then re-sourcing the code at R.
* ,bru
This undoes the last action of ,br thus removing the last
breakpoint. If you wish to remove a different breakpoint, you
need to do that manually.
* ,dbga
This tells R to set the debug status on all of your functions,
i.e. call debug() on them.
* ,dbgf
This tells R to display a list of our functions with the
status on each, regarding whether the function is currently
the subject of a debug() call. The user can then specify on
which functions to toggle that status.
* ,q
This exits the browser, i.e. emits a Q command to the
browser.
* ,dt
This executes the R call you've previously stored in the Vim
variable g:TestRun.
For example, suppose you are testing your code via a call
test(5,12,13). You can store that by typing
:let g:TestRun = "test(5,12,13)"
in Vim. Then anytime you want to run the test, hit ,dt.
