Detect clusters in a hierarchical dendrogram using a variable cut height approach. Uses only the information in the dendrogram itself is used (which may give incorrect assignment for outlying objects).

A variable height branch pruning technique for dendrograms produced by hierarchical clustering.
Initially, branches are cut off at the height maxTreeHeight
; the resulting clusters are then
examined for substructure and if subclusters are detected, they are assigned separate labels. Subclusters
are detected by structure and are required to have a minimum of minModuleSize
objects on them to
be assigned a separate label. A rough degree of control over what it means to be a subcluster is
implemented by the parameter deepSplit
.
A vector of numerical labels giving assignment of objects to modules. Unassigned objects are labeled 0, the largest module has label 1, next largest 2 etc.
