treestats 1.70.5 (2024-08-26)

Updated references.

treestats 1.70.4 (2024-07-17)

Removed C++20 dependency

treestats 1.70.3

Version numbering has improved to include the number of statistics availabe.

treestats 1.1.3

Reduced dependencies, Matrix and RSpectra are no longer required (but availability will improve speed!)
calc_all_stats, calc_topology_stats and calc_brts_stats no longer return a named list, but return a named vector, for ease of rapid calculation across many trees

treestats 1.1.2

Removed dependencies to nodeSub by integrating functions to generate fully balanced and unbalanced into treestats.
Renamed 'calc_balance_stats' to 'calc_topology_stats', and included only statistics that take the topology (without the branch lengths) into account.

treestats 1.1.1

Added the following statistics:

minimum(>0) eigenvalue of the Adjacency matrix
maximum eigenvalue of the Adjacency matrix
minimum(>0) eigenvalue of the Laplacian matrix
maximum eigenvalue of the Laplacian matrix
double cherries
root imbalance
four prong

Renamed eigenvector to eigen_centrality (in line with the analogous function in igraph)

treestats 1.1.0

Add several new statistics:

Colless-corrected
Colless-Quadratic
Total path index
Total internal path index
Average vertex depth
Max Width over Max Depth

treestats 1.0.7

Added checks to each statistic verifying the statistic requires an ultrametric or binary tree - this should avoid some rare instances where memory access violations would pop up when providing a non-binary tree to a statistic assuming a binary input phylogeny. Many thanks to Fien Strijthaegen for pointing this out.

treestats 1.0.6

Added treeness statistic

treestats 1.0.5 (2024-01-30)

Squashed a bug in imbalance_steps that would incorrectly calculate for smaller trees
Added bioRxiv link to DESCRIPTION
Added CITATION file

treestats 1.0.4

Corrected wording of variation in branch length statistics to correctly reflect variance, instead of variation

treestats 1.0.3 (2024-01-12)

First release to CRAN
