Extra functions to cut, label and colour dendrogram clusters
dendroextras provides the slice function as an
alternative to the base cut function. In contrast to
cut, slice returns group membership in dendrogram
order i.e. the first element in the group vector that is returned will be
the leftmost member of the leftmost cluster (cluster #1).
dendroextras provides colour_clusters to colour all of
the edges forming clusters cut by height or number of groups. You can also
set and retrieve the leaf colours (i.e. the terminal nodes) using
set_leaf_colours and leaf_colours.
