A good place to start would be the functions in the package Statistics`ClusterAnalysis. A variety of different distance measures have been implemented in that package. Possibly one of the existing methods is suitable. If not, looking though the code with a text editor should give you some ideas as to how to solve your specific problem. -- To reply via email subtract one hundred and four
