Could anybody indicate me a more general reference(s)
for e1071 functions on fuzzy classification that the articles
that are mentioned in the help?
Or, perhaps, may be someone could explain

1. How the fuzzy membership is calculated. I understand that
if m=1, the classification proceeds as a crisp classification
with the Euclidean distance and that m>1 modifies this
distance to make it fuzzy, but how?

2. What are the main differences among cmeanscl, cshell and
scaclust?

Thanks

Agus
