[Rcpp-devel] How to create a new plugin?

[Dominick Samperi]

The warnings are due to the fact that the plugin looks for Makevars (and
Makevars.win)
in cxxPack/skeleton instead of Rcpp/skeleton. When I copy to
cxxPack/skeleton everything
works. Since it worked without this change perhaps it falls-over to using
Rcpp/skeleton?
