minmax_laplace

Calculates the eigenvalues of the Laplacian Matrix, where the
Laplacian matrix is the matrix representation of a graph, in this case a
phylogeny.
When the R package RSpectra is available, a faster calculation can be used,
which does not calculate all eigenvalues, but only the maximum and minimum.
As such, when using this option, the vector of all eigenvalues is not
returned

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>.
