This was more of a curiosity question. Armadillo and Eigen are great and I will likely use them for most of my purposes. I have just been exploring more of the boost library and was wondering about it. That said, it would be a potentially useful exercise for me when I have some more time to devote to it. You mention starting with the as<>() and wrap() converters. Is there any documentation on developing additional Rcpp functions or should I just go in to the source and try to find my way around?
