cutreeStatic: Constant-height tree cut

In WGCNA: Weighted Correlation Network Analysis

Constant-height tree cut

Description

Module detection in hierarchical dendrograms using a constant-height tree cut. Only branches whose size is at least minSize are retained.

Usage

cutreeStatic(dendro, cutHeight = 0.9, minSize = 50)

Arguments

dendro	a hierarchical clustering dendrogram such as returned by hclust.
cutHeight	height at which branches are to be cut.
minSize	minimum number of object on a branch to be considered a cluster.

Details

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.

Value

A numeric vector giving labels of objects, with 0 meaning unassigned. The largest cluster is conventionally labeled 1, the next largest 2, etc.
