I've just developed edtdbg, a small package that integrates R's debug()
with one's text editor.
Excerpt from the README file:
Goal
The debug() function in R is primitive. My goal was to make it more
usable by integrating it with one's text editor. Hence I wrote the
package here, edtdbg. Its features include:
* As one steps from line to line of code using the debugger, the
cursor in the editor will always follow, i.e. it will alway be on
whatever line the debugger is on.
* One can enable automatic display of user-specified variables.
* One can quickly and conveniently set "breakpoints."
Currently the package is implemented only for Vim. In addition, the
second and third features require the vim-r plugin for Vim. Emacs/ESS
users should easily be able to convert the code; some of the machinery
is already in the code and in the instructions below.
I'm placing the current version of the package at:
http://heather.cs.ucdavis.edu/~matloff/R/edtdbg/edtdbg.tar.gz
http://heather.cs.ucdavis.edu/~matloff/R/edtdbg/edtdbg.zip
Please give me your comments. I probably will upload to CRAN at some
point, possibly after an ESS guru contributes the ESS code. :-)
A note on my Rdsm package for parallel R: The new, much improved
version is just about ready. I'll be uploading Rdsm to CRAN very soon.
I haven't tried it yet, but it looks good from the writeup. One
suggestion: you could use the setBreakpoint function to set
breakpoints, rather than re-sourcing the breakpoint. An advantage of
this is that it lets you set breakpoints in packages.
