ggtree collapse all but

[antoine4ucsd]

Hello I have a big tree (n=29k tips) from which I would like to highlight some clades I defined those clades in the meta which looks like that:

mytree2 <- mytree %<+% meta

then plot it

mytree + geom_tippoint(aes(color=clades,fill=clades)

but as you can see in the attached image, it is too dense. My goal would be to collapse ALL but these taxa. can you help with that? also is there a way to filter prune tree based on edge.length?
