ggdendro package is a set of tools for extracting dendrogram and tree diagram plot data for use with ggplot

ggdendro is a set of tools for extracting dendrogram and tree plot data so that dendrograms and tree plots can be plotted using the package . The ggplot philosophy is to separate clearly the data from the presentation. Unfortunately the plot method for dendrograms plots directly to a plot device without exposing the data. The package resolves this by making available functions that extract the dendrogram plot data.

The reference manual can be accessed from here.

How to reverse distance scale in ggdendrogram and to add label under the distance scale?

I am using ggdendrogram to construct a dendrogram based on Jaccard matrix. Is there a way to reverse the distance scale from 0 - 1 to 1 - 0 and to add text under the distance scale with ggdendrogram? Cheers.

ggdendrogram for a large number of nodes

I'm trying to plot a dendrogram with a large number of nodes using ggdendrogram and it's pretty slow (compared to dendextend for example): set.seed(1) mat <- matrix(rnorm(100*10),nrow=100,ncol=10) dend <-…

Equally spaced out lengths in dendrograms

In this diagram, the main information (most nodes) is on the extreme left side. I want to make the dendrogram easy to read and thus the edges should be proportionally long. Any specific arguments to be used or is it just the data's problem?
