[R] cluster

[Ronaldo Reis Jr.]

Hi,
I have the graph below:

|                  422
|          1       321
|   1
|          1
|32   1
|23
|_______________________

The numbers are points in coordinates (simplified graph).
I need make a cluster analysis of this for identify groups and make a graph 
with this groups under circle.
In R exist several packages for cluster analysis, but, which the package for 
this analysis and graphs?

Thanks for all
Inte mais
Ronaldo
