There is definitely general interest in doing that. And as mentioned earlier
in this thread, there has been previous talk between Ryan (MLPACK), Conrad
(Arma) and myself. It would probably be best to somehow involve Ryan and his
group as they have thoughts (and have considered Swig and other tools).  It
would need some thought, and someone with time and knowledge of both projects
to be involved.

That said, you can of course also start with simple as<>() and wrap()
converters just to get going. Nothing wrong with some explorations and
examples while figuring out the bigger picture.

Cheers, Dirk

| 
|     I am extremely interested in putting in (non-trivial) time into something

| 
|     My question to you is: have you or anyone else started a project like this
|     that I can contribute to? And if not, could someone point me the right way
|     to get started?
| 
|     Thanks!
|

|         | 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:
|         | http://mlpack.org
| 
|         Sure. I am in somewhat regular contact with Ryan Curtin, its lead
|         developer,
|         because of our joint interactions with Conrad and his priceless
|         Armadillo
|         library.  But Ryan is a grad student, and we while we have talked
|         about R
|         binding (meaning the real thing and not just some SWIG interfaces), he
|         is not
|         exactly overflowing with free time. Neither am I.
| 
|         | 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.
| 
|         This makes YOU the perfect candidate to start a project NOW as YOU need
|         IT.
|         And YOU have already worked with both pieces.
| 
|         None of our projects became what they are overnight. You have to start
|         somewhere.  Do it right, do it in the open, and if you do that and
|         have some
|         luck maybe others will join and help.
|        
|         Dirk
