Shooting a little from the hip, but based on the error and a glance at 


you may need to import the 'methods' package.  I see that


has it (and also a corresponding `importFrom(methods,as)`.  I think I usually
deploy a more global 'import(methods)'.  This is needed because Rcpp Modules
does some black magic on the package setup to make everything that needs to
be visible effectively visible.

One way to go about this is to create a minimal package using Rcpp Modules,
and to then make sure you carry each setting of the minimal package over into
your actual package -- that would usually involve imports and declaration.
