Constant-height tree cut
Module detection in hierarchical dendrograms using a constant-height tree cut. Only branches whose size
is at least minSize are retained.
cutreeStatic(dendro, cutHeight = 0.9, minSize = 50)
dendro |
a hierarchical clustering dendrogram such as returned by |
cutHeight |
height at which branches are to be cut. |
minSize |
minimum number of object on a branch to be considered a cluster. |
This function performs a straightforward constant-height cut as implemented by cutree,
then calculates the number of objects on each branch and only keeps branches that have at least
minSize objects on them.
A numeric vector giving labels of objects, with 0 meaning unassigned. The largest cluster is conventionally labeled 1, the next largest 2, etc.

hclust for hierarchical clustering, cutree and
cutreeStatic for other constant-height branch cuts, standardColors to convert
the retuned numerical lables into colors for easier visualization.
