Hi Felipe.
Yes, your phytools version is from late 2015 and I added the interactive
feature in summer 2016
(http://blog.phytools.org/2016/06/interactive-version-of-phylotobackbone.html).
To update all packages you can run (in a fresh R session without any
other sessions open):
update.packag
Hi Felipe.
What version of phytools are you using? A very old phytools version did
not default to interactive mode if no translation table (trans) was
supplied.
Otherwise, I do not know - but it should not be because the tree is not
ultrametric.
All the best, Liam
