Yes I don't like using Rcpp:Function either however it isn't easy to
convert a data.frame into matrix in Rcpp. You have to write code to deal
with factors and non-numeric columns that might be passed in. Also the
original question was asked for SEXP objects. And I'm not sure how you
would deal with those without Rcpp::Function. If there is an easy way I
would be interested in learning about it.
