[datatable-help] kproto - clustMixType - optimal number of clusters

[agent dunham]

Dear community, 

I've a dataset of 430000 rows, and 6 columns (1 continuous, 4 nominal, 1
ordinal).

I'm trying to cluster this data via kproto. 

How can I estimate the optimal number of clusters?
I haven't found anything at clustMixType. Is there anything at any other
package?

Thanks in advance,
