I maintain the geometry package, which integrates the Qhull C library (http://qhull.org) into R. The Qhull function I hook into requires an open FILE handle 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_Consolefile and R_Outputfile only point to open files when CharacterMode == RTerm, not in GUI mode. Therefore my question is, are there any replacements for stdout and stderr that work across all versions of R? All the best, David. -- David C Sterratt, Research Fellow.
