Thanks for reply.
The problem is I don't need to do clustering. What I meant was the
matrix was already in a hierarchical format.
each number before the dot is one layer of the tree
so 1>1.01 > 1.01.01 > 1.01.01.01
so part of lowest nodes of the tree might look like this
so how can I convert the list into such format? each one is a node of
the tree and there are 4 layers.
Also. I'm looking for any interactive dendrogram visualisation.
Thanks in advance.
