Hi. This is because your tree is not fully dichotomous.
> tree<-read.nexus(file="tree.nex")
> is.binary.tree(tree)
[1] FALSE
You can resolve multifurcations with branches of zero length using
multi2di(), e.g.:
> tree<-multi2di(tree)
> is.binary.tree(tree)
[1] TRUE
Hope this helps. - Liam
dear all,
I have a question when I used the pic funtion, it appeared an error:"'phy'
is not rooted and fully dichotomous", I don't understand what's the problem,
the attached file is my phylogenetic information, please check it, I am sorry
to trouble you all, but I really want to solve this
