?hclust
for how to use hclut, for example
hc <- hclust(dist(USArrests), "ave")
Notice that you have to first compute the distance matrix with function "dist" or simmilar.
to get groups see ?cutree for expamle for three grouops use k=3 groups<-cutree(hc,k=3) and then plot using plot(USArrests,col=groups)
I hope this help! In the future, PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html and follow the instructions (read help pages)!
