Rattle is a graphical user interface for data mining in R

Rattle (the R Analytic Tool To Learn Easily) provides a Gnome (RGtk2) based interface to R functionality for data mining. The aim is to provide a simple and intuitive interface that allows a user to quickly load data from a CSV file (or via ODBC), transform and explore the data, build and evaluate models, and export models as PMML (predictive modelling markup language) or as scores. All of this with knowing little about R.

How to interpret a Dendrogram from hierarchical clustering to find optimal number of clusters?

When viewing this, how do we know to find the optimal number of clusters? I used K-means and found the "elbow" on the graph that showed the optimal point but I am having trouble figuring this out from just the dendrogram.
