Hi David,
You are right about this help page which is not so accurrate. I have
modified it with:
"The test differs slightly whether the tree is rooted or not. An
urooted tree is considered binary if all its nodes are of degree three

Yes, I understand that's the general reasoning for why ape refers to
trees with a polytomous root as 'unrooted'.
But if a tree with a basal trichotomy is an acceptable binary tree,
this doesn't jive with the help description for is.binary.tree in ape.

Hi David.
In an unrooted, fully dichotomous tree each internal node is attached to
three & exactly three nodes (some of which are tips). (In a rooted
binary tree one additional internal node exists, the root, which is
attached to only two nodes.) Ancestor & descendant have no meaning until

Hi Emmanuel and the rest of the list,
In some code, I use the ape function is.binary.tree to test if a
phylogeny is fully dichotomous. However, some recent analyses have
made me wonder if this wasn't the right choice. I'm not sure if the
following is a bug report me or me not understand the reason
