But what works fine is if, within the loop, I do the Rcpp-to-double conversion, and then call a version of the function that takes a double as an argument, instead of the SEXP.  So I think there is something going on with passing the SEXP to func, and then using Rcpp::as to convert the SEXP to double.

Yep. I'm still surprised that Rcpp:as works (I thought it would also take a SEXP as an argument), but if it works, then great.
