Hi, I am embedding R into a C++ application. Is it possible to call R functions from different threads? If yes, should I call Rf_initEmbeddedR once or for each thread separately? I know that R is not thread safe and making sure that no simultaneous calls from different threads happen. Now I am working under Windows though I want it to be workable under Linux too.
