Hi, I would like to display error messages and warnings which are generated in R in my own GUI. For normal output we simply had to assign a callback function to ptr_R_WriteConsole and ptr_R_ShowMessage. According to google there should be similar function pointers for error messages. Such as ptr_R_WriteErrConsole. However, I could not find this function pointer in my current R installation (R version 2.8.1 (2008-12-22)). Do I need to install a different R version or is there by now a different way to receive those callbacks? Your help will be greatly appreciated! Thanks, Christian

ptr_R_WriteConsoleEx is what you are looking for. And this is the manual you want to look at: http://cran.r-project.org/doc/manuals/R-exts.html .
