No worries. This can be tricky, and R (and Rcpp) make simple(r) things easy
but sometimes you need to step back and review whether the tooling is
appropriate.
R had an identified weakness with int-based indexi
Apologies for the misunderstanding.
Thanks

I think you misunderstood my previous email (which you chose not to quote).
First:

Thanks, Dirk. Would it matter if I initialize the values in the array to
missing (NA_REAL)?

Dear list
I have written the following function to produce multidimensional arrays using
Rcpp:
NumericVector arrayFromVector(NumericVector input, IntegerVector dim) {
// check for zero-length vectors
if(dim.length() == 0 || input.length() == 0) {
return NULL;
}
long p = 1;
