| ||||||||||||
| Return Type | boolean | ||||||||||||
| Synopsis | IdenticalTrees tests whether the two given trees have the same topology (shape, relation between the leaves). The branch lengths are ignored. The trees must have leaves based on the same labels (first argument of Leaf). If the set of leaf labels differs, IdenticalTrees will return false. | ||||||||||||
| Examples | > t1 := Tree(Tree(Leaf(a,2),1,Leaf(b,2)),0,Tree(Leaf(c,2),1,Leaf(d,2))): > t2 := Tree(Tree(Leaf(a,2),1,Leaf(d,2)),0,Tree(Leaf(c,2),1,Leaf(b,2))): > IdenticalTrees(t1,t2); false | ||||||||||||
