rquartet

The rquartet index counts the number of potential fully
balanced rooted subtrees of 4 tips in the tree. The function in treestats
assumes a bifurcating tree. For trees with polytomies, we refer the user to
treebalance::rquartedI, which can also take polytomies into account.

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>.
