Larger font and gap between leaves in R dendrogram

Question

I have a dendrogram in R, I just can't figure it out.

I will show you what the problem is, please check this: http://img.photobucket.com/albums/v699/rica01/Rplot-1.png

How can I make labels on sheets more and more in between?

Thanks.

Solution: use the set function with the "labels_cex" parameter from the dendextend package.

 # install.packages("dendextend") library(dendextend) dend <- as.dendrogram(hclust(dist(USArrests[1:5,]))) # Like: # dend <- USArrests[1:5,] %>% dist %>% hclust %>% as.dendrogram # By default, the dend has no text size to it (showing only the first leaf) get_leaves_nodePar(dend)[[1]] par(mfrow = c(1,2), mar = c(10,4,4,2)) plot(dend, main = "Original dend") # let increase the size of the labels: dend <- set(dend, "labels_cex", 2) # Now each state has a larger label get_leaves_nodePar(dend)[[1]] plot(dend, main = "A larger font for labels") 

(note that changing the spacing between labels is not currently implemented)
