plot_dendrogram: Plot a dendrogram colored by cluster

In joemarlo/sequenchr: EDA Tools for Sequence Analysis

Description

Plots a dendrogram where the colors of the segments represent cluster membership. Note that the cluster labels may not match the cluster labels in other sequenchr::plot_* functions.

Usage

plot_dendrogram(cluster_model, k, h = 100)

Arguments

cluster_model	a clustering model such as the output from hclust
k	the number of clusters
h	the minimum height to plot the segments. A lower height results in decreased performance

Value

ggplot object

Examples

library(TraMineR)
data(mvad)
seqstatl(mvad[, 17:86])
mvad.alphabet <- c("employment", "FE", "HE", "joblessness", "school",
                   "training")
mvad.labels <- c("employment", "further education", "higher education",
                 "joblessness", "school", "training")
mvad.seq <- seqdef(mvad, 17:86, alphabet = mvad.alphabet,
                   labels = mvad.labels, xtstep = 6)
dist_matrix <- TraMineR::seqdist(seqdata = mvad.seq, method = "DHD")
cluster_model <- hclust(d = as.dist(dist_matrix), method = 'ward.D2')
plot_dendrogram(cluster_model, 5)
