Rearrangement Distances Between Phylogenetic Trees R package TBRDist version 2.0.1 CRAN Task View: Phylogenetics (https://CRAN.R-project.org/view=Phylogenetics) Fast calculation of tree rearrangement distances. For unrooted trees: Subtree Prune and Regraft (SPR), Tree Bisection and Reconnection (TBR), and Replug distances, using the algorithms of Whidden and Matsen (2017) <doi:10.48550/arXiv.1511.07529>. For rooted trees: rooted SPR (rSPR) distance, using the fixed-parameter algorithms of Whidden, Beiko, and Zeh (2013) <doi:10.1137/110845045>.
