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!!

[R] [klaR packages] Weighted kmodes (how to derive the weights?)
Hi. How can I found the specific outcome 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!!
