I don't know of any implementations yet. On the other hand it isn't that hard to get the basics working (see http://nbviewer.jupyter.org/github/lmcinnes/hdbscan/blob/master/notebooks/How%20HDBSCAN%20Works.ipynb http://nbviewer.jupyter.org/github/lmcinnes/hdbscan/blob/mas... for an explanation of the algorithm). The trickier part is getting good performance, but for small datasets that doesn't really matter. Hopefully someone will put together an implementation for R soon.
