reindex_clusters: Reindex cluster labels in ascending order

In SC3: Single-Cell Consensus Clustering

Description

Given an hclust object and the number of clusters k this function reindex the clusters inferred by cutree(hc, k)[hc$order], so that they appear in ascending order. This is particularly useful when plotting heatmaps in which the clusters should be numbered from left to right.

Usage

reindex_clusters(hc, k)

Arguments

hc	an object of class hclust
k	number of cluster to be inferred from hc

Examples

hc <- hclust(dist(USArrests), 'ave')
cutree(hc, 10)[hc$order]
reindex_clusters(hc, 10)[hc$order]
