You could also use this:
Summing3 <- cxxfunction(signature(x="numeric"), '
Rcpp::NumericVector Dvec(x);
double out = sum(Dvec);
return Rcpp::wrap(out);
',plugin="Rcpp")
x <- rnorm(100)
Summing3(x); sum(x)

Dear Rcpp experts,
I have the following bizarre problem. Although the second summing C++
function seems easier than the former, it does not produce the correct
answer. See the following reproducible codes:
##
Summing1 <- cxxfunction(signature(x="numeric
Rainer,
