Hi.
I have two question!
1) Is there any way to draw a dendrogram for k-modes?
I used klaR pacakges for kmodes analysis to deal with categorical variables.
i heard about the "Clustergram"
Url = {http://www.schonlau.net/clustergram.html}
but i only found the example of Clustergram for K-means..'
2)How can I found the result of weighted k-modes?
i did the cluster analysis with weighted kmodes(klaR packages)
like..
==================
a<-kmodes(data, 5, TRUE)
==================
What i want to see is not only the result of clustering but the result of "weight for each attributes".
I found the code for kmodes(https://github.com/cran/klaR/blob/master/R/kmodes.R#L124)
and below codes seems to save the weights for each attribute..
but i do not know exactly how to extract this result by adding another R command...
if(weighted){ ## compute the frequencies of each category for each variable weights <- vector("list", num_var) for (i in 1:num_var) weights[[i]] <- table(data[,i]) } else { weights <- NULL }
Thanks all!!
