avg_ladder

Calculate the avgLadder index, from the phyloTop package.
Higher values indicate more unbalanced trees. To calculate the average ladder
index, first all potential ladders in the tree are calculated. A ladder is
defined as a sequence of nodes where one of the daughter branches is a
terminal branch, resulting in a 'ladder' like pattern. The average ladder
index then represents the average lenght across all observed ladders in the
tree.

Collection of phylogenetic tree statistics,
collected throughout the literature. All functions have been
written to maximize computation speed. The package includes
umbrella functions to calculate all statistics, all balance
associated statistics, or all branching time related statistics.
Furthermore, the 'treestats' package supports summary statistic
calculations on Ltables, provides speed-improved coding of
branching times, Ltable conversion and includes algorithms to
create intermediately balanced trees. Full description can be
found in Janzen (2024) <doi:10.1016/j.ympev.2024.108168>.
