This post describes how to use the
CollapsibleTree package to build an interactive
tree diagram. Explanation and
reproducible code provided
The collapsibletree package is the best option to build
interactive dendrogram with R.
On the chart above, you can click a node to reveal the following branch that is currently collapsed.
The input must be a data frame that stores the hierarchical information.
Basically, each row describes a complete path from the root to the leaf.
In this example, the warpbreaks dataset has 3 columns:
wool, tension and breaks.
# Load library
# install.packages("collapsibleTree")
library(collapsibleTree)
# input data must be a nested data frame:
head(warpbreaks)
# Represent this tree:
p <- collapsibleTree( warpbreaks, c("wool", "tension", "breaks"))
p
# save the widget
# library(htmlwidgets)
# saveWidget(p, file=paste0( getwd(), "/HtmlWidget/dendrogram_interactive.html"))Related chart types
