Hello, Can anyone offer any insight on graphing classification dendrograms with the nodes marked? plot(tree()) produces a nice tree structure but there's no acccompanying text. Thanks, D S.

Hi David,
I found the mva library to be very useful in this case. Functions like hclust()
is pretty useful and you can specify the method you want to use (like
kmeans...etc).
Even use tree(), I think it is possible to add text into it. I had a look at
the tree() documentation by typing:
?tree
and found an example:
library(MASS)
data(cpus)
cpus.ltr <- tree(log10(perf) ~ syct+mmin+mmax+cach+chmin+chmax, cpus)
cpus.ltr
summary(cpus.ltr)
plot(cpus.ltr); text(cpus.ltr)
The last command text(cpus.ltr) adds in the text.
Hope this helps,
Kevin

Hello,
Can anyone offer any insight on graphing classification dendrograms with
the nodes marked?
plot(tree()) produces a nice tree structure but there's no acccompanying
text.
Thanks,

tree.1<-tree(...) plot(tree.1) text(tree.1) eventually as text(tree.1,cex=0.5) if you got a large tree Petr S.

Hi, mva should come from the base -at least for Windows, but I think it does come with the base in any platforms. MASS library is the VR package, which has "Various functions from the libraries of Venables and Ripley, `Modern Applied Statistics with S-PLUS' (3rd edition). " You can get it from CRAN (http://cran.r-project.org/) and compile from source.
