How to label nodes of a dendrogram with mathematical symbols?
I am doing cluster analysis on some set of mathematical objects. The basic R has the functionality to plot mathematical symbols. I want to label nodes of my dendrogram with some mathematical symbols. How to incorporate this in plot function for hclust object? For instance, I want to label my nodes with letters with subscript, e.g.,
T2
How to do this in R?
Solution
Try this:
library(latex2exp)
library(dendextend)
tree <- hclust(d = dist(x = iris[1:20, 1:4])
dend <- as.dendrogram(tree)
labels(dend) <- TeX("$\\pi_2^3 (\\xi_3^4)$")
plot(dend)
