You do not need wrap(X) when X is an Rcpp object such as a NumericMatrix; the
wrap function is called automagically for you (and we call that implicit wrap
As Dale pointed out to you, you generally want simpler and simpler
sub-expression of your problem. And if and when you post a complete example
as you did (which is good -- thumbs up!) also post a mock data generator in R
that allows us to call it to actually make it __reproducible__.
