[Rcpp-devel] Error loading modules

[Romain Francois]

Ok. Now it is much more easier to help.

This works for me:

 > require( anRpackage )
Le chargement a nécessité le package : anRpackage
Le chargement a nécessité le package : Rcpp
 > yada <- Module( "yada", "anRpackage" )
 > yada$hello()
Erreur dans yada$hello() : boom

The key is the second argument of Module.
