Along with getting pqR to work on Windows, I've also been testing it in the context of embedded R, and in the process have found some problems with the examples given of embedded R use. One problem can be seen in R_ReplDLLinit, in src/main/main.c: void R_ReplDLLinit(void) { SETJMP(R_Toplevel.cjmpbuf); R_GlobalContext = R_ToplevelContext = R_SessionContext = &R_Toplevel; R_IoBufferWriteReset(&R_ConsoleIob); prompt_type = 1; DLLbuf[0] = DLLbuf[CONSOLE_BUFFER_SIZE] = '\0'; DLLbufp =...

Dear R developers, i've got a question concerning an embedded R instance. I called the initialization routines as seen in the "writing extensions" guide (Rf_initialize, setup_Rmainloop and R_ReplDLLinit). I also changed the function callback pointer of readconsole and writeconsoleex to my local functions. when i call mainloop there is no problem and the commands are evaluated as expected. because i don't want R to run in an own thread and my app should keep the control i want to use repld...

...sed w/ the *NIX embedding stuff) I did a little experiment to see if I could bind my primary executable. Adding the code below to Rdynload.c seemed to work (in the Windows case). You'll note the remarkable resemblance to AddDLL. :-) My test code calls this to set up its function list just after R_ReplDllinit() just before entering the do1-loop--- though perhaps this should be integrated into some part of the setup procedure for embedding apps.

Dear r-helpers, I have been trying to invoke R from Java in a Windows 2000 computer (unfortunately). All my environment variables seem to be properly set, everything seems to be in order, but I obtaining a Fatal error: unable to open the base package error window. Also, the output of the invoker is Loading RInterpreter library R_HOME: R_HOME=C:/Programas/R RVersion: R_VERSION=1.6.1 whereas

Hi Simon, Widespread errors would have caught my earlier as the way that code is using only one initialization of the embedded R, is used quite a bit, and is covered by quite a few unit tests. This is the only situation I am aware of in which an error occurs. What is a "correct context", or initial context, the code should from ? Searching for "context" in the R-exts manual
