[Rcpp-devel] Another rcpp package for examples

[Dirk Eddelbuettel]

Hi Peter,

Thanks for announcing this here.  Always nice to hear about use cases
involving Rcpp and RInside.

Thanks for pointing to the SVN views. 

There are a few pages on the site that are a bit more restrictive:

   http://www.apsim.info/Wiki/Downloads.ashx
   http://www.apsim.info/Wiki/Access-to-APSIM.ashx

and I am not too sure how/if you can really do that if you have components
(such as R, Rcpp, RInside, ...) licensed under GNU GPL.

What is your understanding there?

This comes up every now and then, and folks would surely love to see a good
tutorial and walk-through.  R Documentation such as "Writing R Extensions"
hints at it at times, but R Core generally declares this as "unsupported".
Which is the position Romain and I take as well as we generally work more on
Linux and OS X anyway.

Regards,  Dirk
