hi--
I am new to R and try to use R cluster my binary data. I use
hierarchical clustering
plot (hclust (dist(x,method=binary),method=average),cex=0.1)
I end up with a cluster Dendrogram. On the left of my dendrogram, there
is scale called Height from 0.0 to 1.0.
I don't understand what does Height represent. If the Height represents
the distance scale between two different data point,
it looks like if I add up the length of each branch, I end up with
distance of some pairs 1. It is not possible the distance
between any data point will greater than 1. Could some help me out?
Hi zhaoshi, please check the documentation for the function using ?hclust. You
may also want to look at a book that uses R/S-plus for cluster analysis.
Venables and Ripley's Modern Applied Statistics with S-plus Chapter 11 may be
of some help. Anupam.
