[R] node stack overflow when extracting labels from a dendrogram

[Oleksandr Moskalenko]

It looks like R 3.0.0 has the same limitation as the 2.x series. When extracting labels from about 30000 node dendrogram (x=labels(h)) R throws an error:

Error in match.fun(FUN) : node stack overflow

Is there a way around it?

Thanks,

Alex
