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? Thanks
