idendro

'idendro' is an interactive dendrogram that enables the user to select and color clusters, to zoom and pan the dendrogram, and to visualize the clustered data not only in a built-in heat map, but also in any interactive plot implemented in the cranvas package.

Note: there is an alternative lightweight version of 'idendro' called idendr0. It is implemented in terms of base R graphics and platform-independent Tcl/Tk GUI, and integrated with the GGobi dynamic interactive graphics. idendr0 is suitable for users who have no cranvas package installed.

Documentation

A paper in the Journal of Statistical Software and idendro vignette.

To install:

  • the latest development version: devtools::install_github("tsieger/idendro", args="--no-multiarch")

The installation of prerequisities is described in the full installation instructions available at https://github.com/tsieger/idendro/wiki.

A simple example:

library(idendro)
hc <- hclust(dist(iris[, 1:4]))
idendro(hc, iris)

Example

Bidirectional integration with interactive cranvas plots:

library(idendro)
library(cranvas)
hc <- hclust(dist(iris[, 1:4]))
qx <- qdata(iris)
idendro(hx, qx)
print(qscatter(Sepal.Length, Sepal.Width, data = qx))
print(qparallel(~., data = qx))

Example

For demos, please run demo(package="idendro").
