Interactive dendrogram with R

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"))
