[Rcpp-devel] (no subject)

[Dirk Eddelbuettel]

Thanks for posting.  Just for the record, and just like the main R lists, we
prefer posts with full (correct) names and some sort of affiliation where
available.  

You do know who you are dealing with when you get reply from me; it seems
polite to offer the same.

Look at the Rcpp attributes vignette.  "Attributes", as we call, is inline in
steroids. You never touch "system()", you never touch ".C()" and of course
you never touch "dyn.load()".

You can do better.  A while back, in the RcppDE package I managed offer
passage of user-defined C++ functions which the DE engine then optimized.
The XPtr class in Rcpp makes that easy.

A couple of days ago I gave a talk at U of C / Booth and worked a similar
example into my slides (see the 2nd set -- available at my 'Presentations' page).

I think that scheme is what you'd want here too. 

Hope this helps. The topic is good:  how to pass user-controlled _compiled_
code through so we should work this out / document it.

Cheers, Dirk
