In R, I have cut a dendrogram into clusters. However some of the clusters
have only few samples. How can I merge the small clusters with nearest big
cuter.
hc <- hclust(dist(USArrests))
plot(hc, cex = 0.6)
rect.hclust(hc, k = 4, border = 2:5)
It gives one cluster with only 2 samples. How can I me
This is not a well defined question, until your notions of "small" and
"nearest" are defined. In your specific example
rect.hclust(hc, k = 3, border = 2:5)
... will do what you are asking for. This is not likely to work in the general
case - imagine that your cluster of size two only meets t
2 matches
