If you are using Rgui (it should work under rterm)
yes indeed, it works under rterm
there is no C-level 'stdout' file stream (the normal state
for Windows GUI programs), so no way to capture it inside R.
Aie ! (I feared this answer). Thanks however for the explanation.
I was looking at pipe(), scan() etc.
So, no hope from this side.
If you have the program, can you not edit it before compiling it?
Adding
#define printf Rprintf
will probably do the trick.
yes thanks, I already though on that, and it works.
But i would have preferred not touching this 3rd party code.
You can always link in a wrapper that defined printf and passes the
arguments to Rprintf.
=====================================
There is another little annoyance (always on WindowsXP + R-2.4.1)
When including both <windows.h> and <R.h>
#include <windows.h>
#include <R.h>
There is a #define ERROR redefinition
#define ERROR ),error(R_problem_buf);} // this one in Rs.h
#define ERROR 0 // in MinGW/.../wingdi.h
It's only a warning, but i would prefer to avoid it
and i'm searching how to avoid it.
Thanks for any idea.
It's documented in 'Writing R Extensions'.
The defines used for compatibility with @Sl{} sometimes causes
conflicts (notably with Windows headers), and the known
problematic defines can be removed by defining @code{STRICT_R_HEADERS}.
PS : compilation details :
