Following a previous post (Label and color leaf dendrogram in r) I have a follow-up question.
My questions are similar to the post mentioned but I wonder can it be done
One more solution to the question is to use the new circlize_dendrogram
function which combined the two packages: circlize and dendextend. You will first need to install them:
install.packages("circlize")
devtools::install_github('talgalili/dendextend')
Here is the code to run:
# YOUR CODE
sample = data.frame(matrix(floor(abs(rnorm(20000)*100)),ncol=200))
groupCodes <- c(rep("A",25), rep("B",25), rep("C",25), rep("D",25))
## make unique rownames (equal rownames are not allowed)
rownames(sample) <- make.unique(groupCodes)
colorCodes <- c(A="red", B="green", C="blue", D="yellow")
## perform clustering
distSamples <- dist(sample)
hc <- hclust(distSamples)
#--------------
# NEW CODE
dend <- as.dendrogram(hc )
library(dendextend)
labels_colors(dend) <- colorCodes
# plot(dend)
dend <- color_branches(dend, k=4)
# plot the radial plot
par(mar = rep(0,4))
# circlize_dendrogram(dend, dend_track_height = 0.8)
circlize_dendrogram(dend)
And here is the resulting plot:
