[R] how to draw the data set processed by hclust?

[Ale? ?iberna]

type
 ?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)!
