As labels often extend outside the plot region it can be. Typically, labels are real numbers. labels(data) returns a named vector of variable labels, where the names match the variable names and the values represent the labels. In hierarchical clustering, you categorize the objects into a hierarchy similar to a tree-like diagram which is called a dendrogram. In my result, the boundary is much higher. For hclust. The colours used for the dendrogram labels are taken from the default colours (see getStockcol) so as to match the colours with other spatial proteomics visualisations such as plot2D. # File src/library/stats/R/dendrogram. In this recipe, we will integrate these two in a single plot. Once you understood how to study the structure of your population, you probably want to compare it with your expectation. Clicking on a branch in the dendrogram plot or in the image will highlight that branch and all. A quick reminder: a dendrogram (from Greek dendron=tree, and gramma=drawing) is nothing more than a tree diagram that practitioners use to depict the arrangement of the clusters produced by hierarchical clustering.
