I have produced a hierarchical clustering of 3,107 U. S. counties based on 1995-2000 migration flows between the counties using a certain non-standard methodology (http://arxiv.org/abs/0807.1550). I have been able to convert the results into a cluster object for use by the `Hierarchical Clustering" package of Mathematica. However, if I try to produce the full (very long) dendrogram or even use the command, say, TruncateDendrogram->{1,25}], , using say Orientation->Right, the result is not readable, being "crammed" into a small space. So, I would like to expand this space by several orders. If this problem can be overcome, I would also like to be able to eventually label the leaves of the dendrogram by the names of the counties. But "For Cluster objects, the LeafLabels option can take a function but not a list or Automatic, as there is no unambiguous mapping between the labels and data points in a Cluster object." So, I am not sure how to proceed in this regard. Paul B. Slater
