Hi,

Is it possible to place the group number in a cluster?

The best example I found was at
https://www.crops.org/images/publications/cs/42/5/1584f4.jpeg (see I, II,
IIIa, IIIb)

It would help to identify the group given by cutree since branches can turn
around and they necessarily are not plotted in order (group 2 is not
necessarily the second  from the left).

Thanks for any help.

All the best,

Antonio
