cluster analysis
Hello. I wonder if anyone can help me with this.
I'm performing cluster analysis by using hclust in stats package.
My data are contained in a data frame with 10 columns, named "drops".
Firs I create a distance matrix using dist:
distanxe <- dist(drops)
Then I perform cluster analysis via hclust:
clusters <- hclust(distanze)
At this point I want to view the tree plot, and use plot:
plot(clusters)
Then, once decided which clusters to select, I start identify:
classi <- identify(clusters)
and click on all cluster...
