[Rcpp-devel] integer and numeric vector

[Romain François]

And now we can use the initializer lists in conjunction with these classes:

Rcpp::wrap( {1,2,3} )
Rcpp::wrap( {1.0,2.0,3.0} )
Rcpp::wrap( {false, true} )
Rcpp::wrap( {(Rbyte)0, (Rbyte)1 } )

I'll tackle CharacterVector and ExpressionVector tonight.
