Cutting the tree
Remember from the video that cutree() is the R function that cuts a hierarchical model. The h and k arguments to cutree() allow you to cut the tree based on a certain height h or a certain number of clusters k.
In this exercise, you will use cutree() to cut the hierarchical model you created earlier based on each of these two criteria.
