[R] dendrogram

[Zhesi He]

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

1.01
|
|__1.01.01
|	|______1.01.01.01
|	|______1.01.01.02
|
|__1.01.02
	|______1.01.02.01
	|______1.01.02.02


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.
Zhesi.
