R help - Oct 2008 - help to debug C codes called from R

Hello everybody,

I have a package with a C codes called from R.
 I want to debug the C functions to check variables values and to include some
breakpoints in the C codes.
I am wondering if anyone knows of any  tools to easily help debug in the R
environment.

Thank you very much for your help.

Arnaud.

This might be Linux specific, I have never tried it on anything else:

R -d gdb

library(<your-package>)

CTRL+C

break <an-entry-point-in-your-package-to-debug>

c

<your-function-to-debug>()

Maybe see also the R extensions manual,
Gabor

You can use whatever debugger you normally use for C code, e.g. 
gdb/insight/ddb if you are using the usual gcc tools to build it.

For details on doing this in Windows, see
