Just to update everyone that I've found the bug in the package, and now the
RcppDend package works fine. You can see the relevant commit here:

The problem was that my NAMESPACE file was missing the two lines:

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.
I took the libe
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 {

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

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
Dear Romain, and other Rcpp-devel members.
I need some help. I've looked into the code Romain posted a few weeks ago,
and I see that I can't change the example from working on double to working
on String.
I keep running into the error of:
no matching function for call to

Thanks Romain and Dirk!
I am currently (slowly) working on developing a package where I would need
some of these skills for specific bottleneck functions. I will get to the
stage of using your code probably in something between 2 to 5 weeks (I
hope).
Once I reach it I will gladly share my progress.
Hello Tal,
I'm trying to express this with the tools available in Rcpp 0.10.3. (And
adding some tools for later versions too, like is<>).
Here is how I would do the first problem:
First break down into functions. We need :

SVN checkout from R-Forge, as always.
The is<> stuff isn't finished, though. SVN head is not that far ahead of
CRAN's 0.10.4.

Thank you Romain and Wush.
Where from can I get the latest version of Rcpp with these new features?
And how may I learn how to use them?
Many thanks,

Hi Tal,
I'm travelling right now, i'll give some additional pointers later.
This is a nice non trivial example, and i hope that the code îve put in
recently (with is<>) can help you so that you dont have to use TYPEOF for
dispatching.
Our exchange at useR is part of my motivation for adding

Here is a script to show you how to access them:
```r
x <- list(a = 1, b = 2, c = list(ca = 3, cb = 4
Thank you for all the responses Dirk.
I will go through them one at a time to see what I can accomplish on my own.
Further questions will follow in the next few weeks (I imagine).
Cheers,
