Extending 'dendrogram' Functionality in R

Offers a set of functions for extending 'dendrogram' objects in R, letting you visualize and compare trees of 'hierarchical clusterings'. You can (1) Adjust a tree's graphical parameters - the color, size, type, etc of its branches, nodes and labels. (2) Visually and statistically compare different 'dendrograms' to one another.

Introduction

Class "dendrogram" provides general functions for handling tree-like structures in R. It is intended as a replacement for similar functions in hierarchical clustering and classification/regression trees, such that all of these can use the same engine for plotting or cutting trees.

However, many basic features are still missing from the dendrogram class. This package aims at filling in some gaps.

The dendextend package extending R core dendrogram functions.

Installation

To install and load dendextend, simply use:

install.packages('dendextend') # stable CRAN version
library("dendextend") # load the package

Usage

Vignettes:

Also ceck out the dendextend tag in stackoverflow for more examples.

A notable sister package for dendextend is heatmaply for creating interactive cluster heatmaps using R (combining dendextend and plotly).

Getting help
