CHANGES in PHANGORN VERSION 2.12.1.1
OTHER CHANGES
o improvements to write.ancestral
o bab got a progress bar, as it might runs for a long time (suggestion by
Bárbara Bitarello).
CHANGES in PHANGORN VERSION 2.12.0
NEW FEATURES
o new function supgma, performing serial sampled UPGMA
(Drummond, Rodrigo 2000)
o new function gap_as_state, treating gaps as a state.
o new function keep_as_tip allows to prune a tree and keep nodes as a tip
(suggested by Hedvig Skirgård)
o nnls now can estimate trees with calibrations and tip dated trees
o the functions Descendants, Ancestors, Siblings, mrca.phy now also accept a
character vector for the node argument and not only integers.
o 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.
o Joint reconstruction for ML is now available.
o Improvements to several plot functions to get nicer plots out of the box.
Nicer defaults for plot.pml, mainly for rooted trees.
o 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.
o plot.networx gets two additional arguments, direction as in plot.phylo and
angle to rotate the network.
o new function composition_test, indicating possible problems with base /
state composition, similar to the test in iqtree.
OTHER CHANGES
o 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".
o some improvements to pmlPart.
o the sankoff algorithm has been rewritten.
BUG FIXES
o pml_bb roots the tree, if method is either ultrametric or tipdated. Fixes
problem when modelTest object was supplied.
o nnls.tree now checks if the tree has singletons.
CHANGES in PHANGORN VERSION 2.11.0
OTHER CHANGES
o Vignettes have been reorganised, rewritten and vastly improved thanks to
Iris.
o small improvements to plot.codonTest, plot.networx
o rell bootstrap values are now computed by default in optim.pml / pml_bb
BUG FIXES
o fixed bug which caused warning on CRAN
o densiTree does not draw an empty plot any more
o Replace rgl.texts with texts3d, pull request by Duncan Murdoch (thanks)
o changes in read.nexus.splits and read.nexus.networx to work with the
moving targets SplitsTree6/SplitsTreeCE
CHANGES in PHANGORN VERSION 2.10.0
NEW FEATURES
o several improvements to simplify workflow and flatten learning curve.
o new function pml_bb, combining generation of starting trees, pml and
optim.pml and allowing modelTest object as input.
o tipdated phylogenies estimation (was with limitations possible before,
but not documented).
o Mkv model, edge length and rearrangements only work for ultrametric and
tiplabeled phylogenies so far.
o Added experimental version of RELL bootstrap (Minh et al. 2013 Ultrafast
Approximation for Phylogenetic Bootstrap).
o modelTest now tests several models for USER defined data.
OTHER CHANGES
o some default values of of pratchet changed
o updated, improved and reorganized several vignettes.
o function allSitePattern got an argument additional type.
CHANGES in PHANGORN VERSION 2.9.0
BUG FIXES
o modelTest did not work if no tree was supplied
NEW FEATURES
o some tidy functions: glance.phyDat, tidy.modelTest
OTHER CHANGES
o dist.ml is a lot faster for the JC69 and F81 models if there are no
ambiguous sites present.
o added a few helper function to simplifiy some workflows (e.g. modelTest)
CHANGES in PHANGORN VERSION 2.8.0
BUG FIXES
o Use USE_FC_LEN_T in the C prototypes of LAPACK functions to correspond to
code produced by gfortran >= 7. The mechanism was introduced in R 3.6.2
and is planned to make its use obligatory in R 4.2.0.
o bug in dna2codon fixed.
o codon models (codonTest) most likely did not work properly for models
other than the standard code.
NEW FEATURES
o free rate model
o Mkv model (so far only for rooted trees)
o better support for ultrametric and time trees
OTHER CHANGES
o optim.pml has internally been reorganized to be easier to maintain and
extend.
o pml.control got an additional argument tau which controls the minimal edge
length during optimisation.
o trees constructed with allCompat, maxCladeCred now have support values
stored in the node.labels
o switched from magrittr %>% to the native pipe |>
dropped dependency on magrittr
CHANGES in PHANGORN VERSION 2.7.1
BUG FIXES
o several bug fixes in parsimony code
CHANGES in PHANGORN VERSION 2.7.0
BUG FIXES
o several bug fixes, e.g. which called bootstrap.pml and pratchet to crash
OTHER CHANGES
o internal functions for handling bipartitions have been harmonized with ape
and some functions like maxCladeCred are faster
CHANGES in PHANGORN VERSION 2.6.0
NEW FEATURES
o transfer bootstrap (Lemoine et al. 2018)
o pratchet saves trees visited during search, which can be used as
(approximate) bootstrap values
CHANGES in PHANGORN VERSION 2.6.0
NEW FEATURES
o rewritten fitch algorithm to be more memory efficient, often faster
and without limitation on the number of states
o dist.hamming may handle larger datasets and can be faster
o add Laguerre quadrature as option for discrete rate classes (experimental)
o additional genetic codes for codon models.
OTHER CHANGES
o conversion between alignment formats is faster and more memory efficient,
allowing the handling of larger datasets
o changed R dependencies to 3.6.0 mainly to supply nicer palettes via
hcl.colors()
o lots of small improvements to especially for codon models
o tests are now done by tinytest, dropped dependencies on testthat, vdiffr
o all vignettes are now based on Rmarkdown
o pmlPart and pmlMix are a bit more robust
CHANGES in PHANGORN VERSION 2.5.4
NEW FEATURES
o dist.ml, dist.hamming, dist.logDet and dist.p also take DNAbin or
AAbin objects as input
BUG FIXES
o bootstrap.pml returned an error with argument optNni=T
Best practise is to always use TRUE and not T as shortcut
OTHER CHANGES
o several more unit tests
CHANGES in PHANGORN VERSION 2.5.2
NEW FEATURES
o pratchet, optim.parsimony, optim.pml all may now return trees with
multifurcations in case duplicated sequences are discovered. This may
lead to speeding up computations and improved tree topology search.
o function codonTest which adds codon models to detect positive selection
(M1a, M2a) and several options to estimate codon frequencies
(F3x4, F1x4). Can be pretty slow and still experimental.
o broom type tidy function for several objects to easier compare models
o new "equal_angle" layout for 2D-networks (now the default), gives usually
nicer layout of phylogenetic networks
o tiplabels, nodelabels, edgelabels from ape work for plot.networx if
plotted with base R
OTHER CHANGES
o several small improvements to more intuitively use pml and phyDat
objects, like subsetting phyDat objects with "[i, j]".
o several more unit tests
o two new contributors, Keren and Richel
o optim.parsimony, pratchet, pmlMix and pmlPart may return the current best
tree or object when interrupted.
o roxygen2 is used to generate NAMESPACE file
CHANGES in PHANGORN VERSION 2.4.0
NEW FEATURES
o new function add.tips
BUG FIXES
o midpoint works now for trees with only 2 tips
o densiTree, bug report by Richel Bilderbeek
o tree rearrangement in optim.pml return tree with double edge matrix
o phyDat should work now for named vectors
OTHER CHANGES
o many more unit tests
o more consistent coding style
o flashClust and seqLogo are not suggested packages any more
CHANGES in PHANGORN VERSION 2.3.0
NEW FEATURES
o new function mast to compute the maximum agreement subtree
