A phylogenetic tree scaled by time, including the contemporary taxa as a special case.

Methods

  • branchCount
    • the total number of branches in the tree (returns nodeCount() - 1)
  • directAncestorCount
    • the total number of nodes in the tree that are direct ancestors (i.e. have a single parent and a single child, or have one child that is a zero-branch-length leaf).
  • extantCount
    • the total number of extant leaves in the tree (leaf nodes with age 0.0).
  • hasOrigin
    • returns true if this tree has an origin node (defined as a root node with a single child.
  • leafCount
    • the total number of leaf nodes in the tree (leaf nodes with any age, but excluding zero-branch-length leaf nodes, which are logically direct ancestors).
  • nodeCount
    • the total number of nodes in the tree (both leaf nodes and internal nodes).
  • rootAge
    • the age of the root of the tree.
  • taxa
    • the taxa of the tree.
  • treeLength
    • the total length of the tree
