Hi John,
I'm not familiar with any such function either. However, a handy trick
for doing this sort of thing is changing the branch lengths of
descendant nodes to zero and using the ape function di2multi to
collapse those edges, creating a polytomy.
Now, it isn't clear to me from your email
Hi Liam and David,
Thanks for the code! It will be very useful for the trees I'm working with. Two
clades are large, and I need to collapse them for diversitree.
Best,
John
