Maybe what you want is more easily done with the RNGs from C++ (esp
C++11),

If you go with something different from R, I've had good luck with Tina's RNG. (TRNG) It's a fairly complete, fast, and easy to use C++ library... there might even be a reason to wrap it for Rcpp someday. Krzysztof
The model is to call set.seed(somenumber) from R before going to C++, and being assured that a) you get the same stream in C++ as you would in R as well as b) that you can continue fine in R once you are back. What you want is a little different. It may well be supported, but maybe just not (yet ?) by us. Or it may not be supported. Please keep working
at
it, this would be useful to sort this out. Just because you can get the integer seed via R from C++ does yet mean
that
the generator is a sane state. Just saying... Dirk -- Dirk Eddelbuettel | edd at debian.org | http://dirk.eddelbuettel.com
