Hi everyone! :)
I have a question and did not find any answer by personal search. I would like to make a heatmap with categorical variables (a bit like this one: heatmap-like plot, but for categorical variables ), and I would like to add on the left side a phylogenetic tree (like this one : how to create a heatmap with a fixed external hierarchical cluster ). The ideal would be to adapt the second one since it looks much prettier! ;)
Here is my data:
- a newick-formatted phylogenetic tree, with 3 species, let's say:
- a data frame:
x<-c("species 1","species 2","species 3") y<-c("A","A","C") z<-c("A","B","A") df<- data.frame(x,y,z)
(with A, B and C being the categorical variables, for instance in my case presence/absence/duplicated gene).
Would you know how to do it?
Many thanks in advance!
