ose a hanging tree is shown in Figure 2.18(a) and the tree has been

a variable called model. This tree can be cut to generate subtrees

maximum subtree height as two using the following code. The

subtrees are shown in Figure 2.18(b), where it can be seen that

as led to three clusters, i.e., a cluster of data point labelled by A,

of data points labelled by B and C as well as a cluster of data

belled by D and E.

cutree(model,h=2)

ging tree can also be cut for a specified cluster number. The code

low cuts a hanging tree into two clusters. Figure 2.19 shows the
