R devel - Jan 2014 - How to debug an R package (with C code)

Hi all,

Sorry to bother you.

I am a beginner in R programming. I have encountered some problems when I
modified a R package with C code.
I would like to modified the C code within the R package, and want to debug the
C program. But I have no idea how to debug this kind of R package.

In the package, a R file named aaa.R use the interface .call(bbb.c, ...) to call
the C code named bbb.c.
And what I did is that I resourced aaa.R and ran it in R Stdio again, after
modifying bbb.c. But there is nothing happened.
I am very sure that the all the path of R file and C file is correct. And I am
using Windows operating system.

Could anyone give me a few pointers on how to debug R packages (or extensions
with C++/C code)? If possible, Could you please give me an simple example or
some command lines?


Regards,
Saisai
