Tal,
You were close. The error you got indicated that some of (our) wrapping
around (our) class String was missing somehow. String is pretty new; Romain
just added it a few month ago under funding by Hadley -- and I am still
pretty unfamiliar with it.
Which is why I always go back to std::stri
Hello Dirk,
Your modifications/corrections are VERY helpful, thank you! (also, thank

One more question/improvement - is it possible to have it return whatever
value is inside the "label" attr?
For example, running the

Dear Dirk and Rcpp-devel members,
I am currently passing a multidimensional (N > 2) array (i.e.
array(NA, dim = rep(3,5)) ) from R via Rcpp using
"in C++:"
//[[Rcpp::export]]
Rcpp::List check_arrayC (Rcpp::NumericVector x, Rcpp::IntegerVector modes){
//do stuff to x
return Rcpp::List::create

I suspected that this is the case.
Will do - thanks.

Hi Dirk,
N could be anywhere between 3-10.
Thanks! I will definitely look into how to do those.
Also, if
Rcpp::NumericVector vec3 =Rcpp::NumericVector( Rcpp::Dimension(4, 5, 6));
In this case, how do we access element vec3[1,2,3]?
Thanks again,
James

Hi Romain and Dirk,
Sorry I did not see Romain's earlier response. That is very helpful!
Thank you both for your prompt assistance and for developing such a useful
tool.

Just a suggestion re: recursion with Rcpp, yet another nice way we can
recurse is through using the sugar lapply:
-
#include
using namespace Rcpp;
// [[Rcpp::export]]
RObject add_attr(RObject x_) {
RObject x = clone(x_);
if (is(x)) {
x = wrap( lapply( as(x), add_attr ) );
} else {
Dear Dirk, Romain, Kevin, and others.
Since I am currently actively working on extending the dendrogram object in
R, I have a real interest in finding and solving some of the major
bottlenecks of dendrogram manipulation.
Thank you all for all of your help and suggestions thus far.

And even if you're not distributing from source, telling (windows)
users to install rtools and then use install_github is not a big
barrie
