2012-08-21: 1.01-2 . Added the stats routine hcass2 to the package to avoid calling undocumented internal function in the base distribution of R. 2012-03-02: 1.01-1 . Added citation 2011-03-20: 1.01 . Fixed incorrect clustering with methods "centroid" and "median". Thanks to Chi Ming Yau and Daniel Müllner for pointing out the error and suggesting a fix. . Speed now for the most part back up to the level experienced with 1.00-2 but still capable of working with larger data sets. 2011-02-06: 1.00-3 . Fixed overflow errors when the number of clustered objects is over ~45000. The code should now be able to cluster as many as 65000 objects, given enough memory. 2010-07-19: 1.00-2 . added a timing example in the help file 2010-02-19: 1.00 . added a wrapper called hclust so a fast version of hclust is used automatically after loading the package 2009-11-13: 0.10-1 . flashClust now checks that the input distance actually contains some data
