[Rcpp-devel] Dynamic Wrapping and Recursion with Rcpp - using an R function?

Just make sure you clone the initial list once, or use another C++
data structure (e.g. std::vector) that can grow efficiently.

Alternatively, you could create your own alternative to as.dendrogram
that doesn't create a hierarchical structure.  (That's what I'd try
first)
