There is also Davor's trick of getting the C++ function pointer---this avoids the 'going back to R' overhead. ?But it is not really clean to call an API that way if the API decided to close off those access points...
Eh? Haven't seen that before -- where does it live? Let's doc it if it's sane... -xian

As I wrote _in the very next paragraph_ of the email you quote from ;-) :
-- Package rgam on CRAN is one place
-- previous mails here as e.g. Romain's second post in the this thread

It's Romain's trick, really, as you can see from the thread Dirk mentioned. I was just the first to use it in a CRAN package. Davor
