![]() With the keys icoord and dcoord give the x and y coordinates of each Segments of the diagram with the corresponding distance. Show how you can use the data returned by dendrogram to label the horizontal How can I annotate the distance along each branch of the tree using dendrogram so that the distances between pairs of nodes can be compared? Nor a translation ( mat + offset) of the entire data set change the relative Is based on distances between the points, and neither a reflection ( -mat) The arrays mat and 1-mat produce the same clustering because the clustering Why does mat and 1-mat give identical clusterings here? ![]() Clustering is based on the distance between these points. In your example, mat is 3 x 3, so you are clustering M-dimensional space, or a one-dimensional array containing the condensed distance matrix. The input to linkage() is either an n x m array, representing n points in
