R help - Jul 2007 - Ideal number of clusters using the Fanny algorithm

Hello,
Could someone please let me know the procedure for determining the
'best'
solution with regards to the number of clusters using the Fanny algorithm
for computing fuzzy clusters? The function requires a specification of the
number of clusters a priori, but I am interested in determining what number
of clusters would result in the ideal fit with the data. Any
help/advice/pointers to resources on the WWW would be greatly appreciated.
Thank you.
Srikanth.
