Package 'birch' was removed from the CRAN repository.

Formerly available versions can be obtained from [the archive][1].

Archived on 2014-05-30 as long-standing memory access errors leading to segfaults were ignored.

> Therefore, your performance comparison might be hampered by implementation errors. You will most likely not get any meaningful performance data with respect to the algorithm itself, instead it will be influenced heavily by the implementation problems of birch. If you want a fair comparison you should either fix the package (might be hard) or look for a different implementation.
