...le as one of its arguments. I had set this file handle to stdout, but now R check NOTEs the presence of stdout, and the CRAN maintainers asked me to get rid of these NOTEs. Including the following defines means the checks are passed on CRAN: #ifdef WIN32 extern FILE * R_Consolefile; extern FILE * R_Outputfile; #else #include <Rinterface.h> #fi #undef stderr #define stderr R_Consolefile #undef stdout #define stdout R_Outputfile However, this does not work on Rgui.exe, when the above leads to a crash. Looking at http://svn.r-project.org/R/trunk/src/gnuwin32/system.c it would appear that R_Consolef...

In R-2-4-branch r39548, Rcons_vprintf is called from stdout_vfprintf when R_Outputfile is NULL. When called and output is greater than R_BUFSIZE, output is truncated to R_BUFSIZE.

I would like to redefine some R print functions (Rprintf for example) so that they don't print to stdout, but save the output in a global string array. I can compile and link my definition of Rprintf into a library and load it with dyn.load. I don't get an error message, but afterwards the original function is still valid, my new version isn't executed. Is there a way to change R

...ce c generated connection objects onto the Connection array and then use sink(), but that only works for stdout. Another way is to enhance the default stdin, stdout, stderr reading and writing routines to test for the existence of user provided routines, similar to the way stdout_vfprintf tests R_Outputfile.

Hi, I'm trying to understand (mostly from the R-exts manual) how to use the callbacks declared in Rinterface.h. As a first attempt, I'm trying to redefine ptr_R_WriteConsole in a very trivial manner. Here's my code: --------------- $ cat altr.c int Rf_initialize_R(int ac, char **av); #define R_INTERFACE_PTRS 1 #include <Rinterface.h> extern int R_running_as_main_program;

When I originally implemented connections in R 1.2.0, I followed the model in the 'Green Book' closely. There were a number of features that forced a particular implementation, and one was getConnection() that allows one to recreate a connection object from a number. I am wondering if anyone makes use of this, and if so for what? It would seem closer to the R philosophy to have
