hs_hclust_cutoff: Plot clusters on hclust object at given height.

In CMET-UGent/MicroRaman: Phenotyping of microbial Raman spectroscopy data

Description

An easy exploratory way to draw clusters at a given height on a dendrogram.

Usage

hs_hclust_cutoff(dend, h = 0.75, bordercol = "red", ...)

Arguments

dend	a hclust object
h	cutoff distance for the clusters to be plotted (defaults to 0.75)
bordercol	the color of the border
...	other parameters passed on to plot.hclust

Value

a matrix with the assigned clusters for each leaf (in the case of Raman data each cell)

Examples

# Load hyperSpec object
data("hs_example")

# Convert to MassSpectrum object
hs.x.proc <- hs_preprocess(hs_example)

# cluster cells
hclust_obj <- hs_hclust(hs.x.proc, dist_method = "bray",
clust_method = "hclust")

# Draw cutoff
hs_hclust_cutoff(hclust_obj)
