With the aid of R, perform hierarchical clustering for the following

OTUs measured on characters x and y. For dist use method="euclidean"

and for hclust use method="complete". Note with which OTUs C clusters.

x y

A 1.0 9.0

B 2.0 8.0

C 4.0 6.0

D 5.5 4.5

E 6.5 3.5

F 8.0 2.0

Now repeat the process for all OTUs except D, and observe the cluster

membership of C. Performa scatter plot for OTUs A,. . . ,F using the plot and

points functions, and explain why C changed its group membership when D

was omitted.

Note: OTUs arranged like this can create other problems when singlelinkage

clustering is used: see Section 10.4.2 and Everitt and Dunn (2001) for

a discussion of chaining.
