R help - Jan 2010 - ANNOUNCE: edtdbg debugging tool

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.
