WebIn hierarchical cluster displays, a decision is needed at each merge to specify which subtree should go on the left and which on the right. Since, for n observations there are n-1 merges, there are 2^ { (n-1)} possible orderings for the leaves in a cluster tree, or dendrogram. WebCuts a tree, e.g., as resulting from hclust, into several groups either by specifying the desired number (s) of groups or the cut height (s). Usage cutree (tree, k = NULL, h = NULL) Arguments At least one of k or h must be specified, k overrides h if both are given. Details hevosurheiluWebIn hierarchical cluster displays, a decision is needed at each merge to specify which subtree should go on the left and which on the right. This algorithm uses the order suggested by Gruvaeus and Wainer (1972). At a merge of clusters A and B, the new cluster is one of (A,B), (A',B), (A,B'),(A',B'), where A' denotes A in reverse order. hevosurheilu arkisto

"To create a merged hclust object, you can use <<- safely inside a custom environment created using new.env. There may be other ways to create a merged object two at a time without using <<-. Hopefully, someone can throw a light on it. I tried to use do.call ('merge', list ( dendrograms of h1, h2, h3, h4 ). " - Hclust merge
