phangorn 2.12.0

NEW FEATURES

• new function supgma, performing serial sampled UPGMA (Drummond, Rodrigo 2000)
• new function gap_as_state, treating gaps as a state.
• new function keep_as_tip allows to prune a tree and keep nodes as a tip (suggested by Hedvig Skirgård)
• nnls now can estimate trees with calibrations and tip dated trees
• the functions Descendants, Ancestors, Siblings, mrca.phy now also accept a character vector for the node argument and not only integers.
• Ancestral state reconstruction was rewritten. The output of ancestral.pars and ancestral.pars could return different objects. anc_pml and anc_pars are now prefered over ancestral.pml and ańcestral.pars. Output is now an object of class ancestral, which contains tree with node labels, the original alignment and reconstructions. The should be considered experimental as the internals of this function might change in future. Ancestral states of constant sites are now always this state.
• Joint reconstruction for ML is now available.
• Improvements to several plot functions to get nicer plots out of the box. Nicer defaults for plot.pml, mainly for rooted trees.
• plotAnc got an argument scheme allowing to use different color schemes, especially for amino acid models shared with image.AAbin and assumes an ancestral object.
• plot.networx gets two additional arguments, direction as in plot.phylo and angle to rotate the network.
• new function composition_test, indicating possible problems with base / state composition, similar to the test in iqtree.

OTHER CHANGES

• pml.control got an argument statefreq, which controls if "empirical" or (ML) "estimated" state/base frequencies are used/computed. The change of the default to "empirical" speeds up functions modelTest and pml_bb/optim.pml. However estimates will differ to previous versions, which were implicitly using "estimated".
• some improvements to pmlPart.
• the sankoff algorithm has been rewritten.

BUG FIXES

• pml_bb roots the tree, if method is either ultrametric or tipdated. Fixes problem when modelTest object was supplied.
• nnls.tree now checks if the tree has singletons.
