Plots the cost of successive merges in a hierarchical clustering
plot.hclust.trace(h,k=1:10)
h |
an hclust object |
k |
a vector of the cluster cardinalities to plot |
The trace shows, for each merge, the distance of the clusters which were merged. This is useful for determining the appropriate number of clusters. An interesting number of clusters is one that directly precedes a sudden jump in distance.
