run into a variety of difficulties; the two most crucial difficulties
are enumerated below.
1. Where is the 'm' parameter in FANNY?
In _Finding Groups in Data: An Introduction to Cluster Analysis_
(1990) by Kaufman & Rousseeuw, the authors discuss the FANNY
algorithm. On pages 189-190, they attempt to demonstrate an

The 'hclust' function is based an Algorithm contributed to STATLIB
by F. Murtagh and the code is written in C.
Probably the differences between agnes and hclust causes from the different code and the different imp...
