dendrogram_plot_col: Plot dendrogram

In specmine: Metabolomics and Spectral Data Analysis and Mining

Description

Plot dendrogram of hierarchical clustering results with different colors

Usage

dendrogram_plot_col(dataset, hc.result, classes.col, colors = NULL, title = "", 
lab.cex = 1, leg.pos = "topright", label_samples=NULL,...)

Arguments

dataset	list representing the dataset from a metabolomics experiment.
hc.result	object of class hclust with the clustering results.
classes.col	string or index indicating what metadata to use to color the leafs.
colors	vector with the corresponding colors of the metadata classes.
title	title of dendrogram.
lab.cex	the magnification to be used for x and y labels relative to the current setting of cex.
leg.pos	position of the legend.
label_samples	string or index indicating what metadata to use to name the leafs. If not provided the name of the leafs will remain the samples names.
...	other parameters for plotting.

Examples

  ## Example of colored dendrogram
  library(specmine.datasets)
  data(cachexia)
  hc.result = hierarchical_clustering(cachexia)
  dendrogram_plot_col(cachexia, hc.result, "Muscle.loss", 
  title = "Example")
