However, one can obtain a total ordering by using the leaf-ordering algorithm developed by Bar-Joseph et al.

WebJan 8, 2024 · hclust [in stats package] agnes [in cluster package] We can perform agglomerative HC with hclust. First, we compute the dissimilarity values with dist and then feed these values into hclust and specify the agglomeration method to be used (i.e. “complete”, “average”, “single”, “ward.D”). We can plot the dendrogram after this.
