Dear Rcpp developers,
Firstly, many thanks for your work on Rcpp. It has saved me countless hours (or is that months?) of simulation time.
I'm a big fan of RcppArmadillo and Armadillo. Recently I came across MLPACK, which is a large and useful C++ machine learning library that uses Armadillo:

If you have the time to do so, I humbly request for an official RcppMLPACK package. I believe other people will also find it useful. I'm currently copying and pasting code out of MLPACK into my own package, but this is not the most friendly solution.
