I think so. 

And the dreaded '(fresh)' in the second line may be hard to avoid. We need
to create R objects managed by R's memory management facilities -- once we
return something to R, it treats it like an object it created. That makes
external re-use somewhat difficult per my reading of Writing R Extensions.

If you can think of another way I'd be all ears. 

Cheers,  Dirk
