First of all thanks a lot to you both for all the replies, they have been of great help to me!
I got the basic embedding running, however I still have some issues to solve in order to complete the interface to R I am working on: 1. I initialize with Rf_initEmbeddR(). - Is there a way to have more than one R "state" (per single thread)? Or is everything necessarily global? - I also read somewhere that the fpu settings may be touched. Is there a way to make sure that this is not the case? Is this related to fpu_setup()? 2. I create a string and parse it via Rf_mkString() and R_parseVector() (yes I protect/un-protect the SEXPs). - Is it possible to obtain the precise error message, like "unexpected symbol in..." (as would be reported by R.exe) in case of error as a const char* string? - If I pass a wrongly escaped string (for instance 'ggsave("C:\gtest.png")', please notice the missing \) I get on stderr: Error '\g' is an unrecognized escape and I get a crash. This does not happen if for instance i try to parse 'rnorm(10a10)' in which case I get the error flag and the NULL ptr return. I suspect I need to initialize something / set a callback to avoid this but I am not sure... 3. I eval with R_tryEvalSilent(). - Again, is it possible to obtain the precise error message in case of evaluation error as would be reported from R.exe? 4. Regarding the returned result of evaluation. - What is the correct way to obtain a const char* string representing the result as would be "printed" in the R shell by executing a command (for instance "summary(c(1,2,3))") ? - Why is the return type (as reported from typeof in R and TYPEOF in C) of "summary(c(1,2,3))" a double? Any help / feedback on these issues would be greatly appreciated. Thanks again. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
