[R] help with hclust

[Madeleine Seeland]

Hello,

I have two questions regarding hclust:

1) First I would like to cut a hclust tree at a specific height and receive the cluster similarity at this height. 
2) Next, I would like to receive all clusterings up to a given tree height that fulfill a minimal required similarity (i.e., the inner cluster similarity of all clusters needs to fulfill a given similarity value). How can I achieve that?

I would appreciate your help!

Best regards,
Madeleine
