       Andrea where can I find the distribution map code you show me (how
to write a distribution map in 6 lines of code
------------------------------
      Hi,
Presuming you were referring to me, it's Adrian and not Andrea :)
The code is in my bundle MoosLiDevelopment, but because it is only 3 lines
i've extracted it below:
    | engine serializedCollection |
    engine := ClusterEngine with: aCollection using: distanceBlock.
    engine hierarchicalClusteringShowProgressUsing: #averageLinkage.
    serializedCollection := engine dendrogram collect: #yourself.
where:
aCollection: is your collection of elements you want to cluster
distanceBlock: is a block that returns the distance between any 2 elements
of your collection (eg. Euclidean distance for numerical proprieties of
elements)
serializedCollection := the result of the clustering, the serialized version
of the collection
Sorry for the late answer, but i was away for a few days.
   Ciao,
   Adi
