unce/extinct_extant_chapter (see the diagram for a visual explanation) It's not the fastest or most elegant implementation possible... but it works. (Apologies if this last option is not relevant to your use-case) Best, Ross -- Forwarded message -- From: Rob Lanfear Date: Th

You may look into treedist in phangorn (but just does pairs of trees, I believe) or dist.multiphylo in distory (polynomial time, but I don't think it's RF distance), or dist.topo in ape (but again, pairwise and not RF). There's also RMesquite (http://rmesquite.r-forge.r-project.org/) to have R jus

2013-09-19 Thread Rob Lanfear
Hi All, I'm looking for a method to calculate a pairwise distance matrix of RF distances between a set of trees. Specifically, I know it's possible to do this in linear time (relative to the number of taxa), using an algorithm proposed in 1985[1]. This algorithm is implemented in various places (
