ape - Analyses of Phylogenetics and Evolution

Functions for reading, writing, plotting, and manipulating phylogenetic trees, analyses of comparative data in a phylogenetic framework, ancestral character analyses, analyses of diversification and macroevolution, computing distances from DNA sequences, reading and writing nucleotide sequences as well as importing from BioConductor, and several tools such as Mantel's test, generalized skyline plots, graphical exploration of phylogenetic data (alex, trex, kronoviz), estimation of absolute evolutionary rates and clock-like trees using mean path lengths and penalized likelihood, dating trees with non-contemporaneous sequences, translating DNA into AA sequences, and assessing sequence alignments. Phylogeny estimation can be done with the NJ, BIONJ, ME, MVR, SDM, and triangle methods, and several methods handling incomplete distance matrices (NJ*, BIONJ*, MVR*, and the corresponding triangle method). Some functions call external applications (PhyML, Clustal, T-Coffee, Muscle) whose results are returned into R.

brms - Bayesian Regression Models using 'Stan'

Fit Bayesian generalized (non-)linear multivariate multilevel models using 'Stan' for full Bayesian inference. A wide range of distributions and link functions are supported, allowing users to fit -- among others -- linear, robust linear, count data, survival, response times, ordinal, zero-inflated, hurdle, and even self-defined mixture models all in a multilevel context. Further modeling options include both theory-driven and data-driven non-linear terms, auto-correlation structures, censoring and truncation, meta-analytic standard errors, and quite a few more. In addition, all parameters of the response distribution can be predicted in order to perform distributional regression. Prior specifications are flexible and explicitly encourage users to apply prior distributions that actually reflect their prior knowledge. Models can easily be evaluated and compared using several methods assessing posterior or prior predictions.

paleotree - Paleontological and Phylogenetic Analyses of Evolution

Provides tools for transforming, a posteriori time-scaling, and modifying phylogenies containing extinct (i.e. fossil) lineages. In particular, most users are interested in the functions timePaleoPhy, bin_timePaleoPhy, cal3TimePaleoPhy and bin_cal3TimePaleoPhy, which date cladograms of fossil taxa using stratigraphic data. This package also contains a large number of likelihood functions for estimating sampling and diversification rates from different types of data available from the fossil record (e.g. range data, occurrence data, etc). paleotree users can also simulate diversification and sampling in the fossil record using the function simFossilRecord, which is a detailed simulator for branching birth-death-sampling processes composed of discrete taxonomic units arranged in ancestor-descendant relationships. Users can use simFossilRecord to simulate diversification in incompletely sampled fossil records, under various models of morphological differentiation (i.e. the various patterns by which morphotaxa originate from one another), and with time-dependent, longevity-dependent and/or diversity-dependent rates of diversification, extinction and sampling. Additional functions allow users to translate simulated ancestor-descendant data from simFossilRecord into standard time-scaled phylogenies or unscaled cladograms that reflect the relationships among taxon units.

datelife - Scientific Data on Time of Lineage Divergence for Your Taxa

Methods and workflows to get chronograms (i.e., phylogenetic trees with branch lengths proportional to time), using open, peer-reviewed, state-of-the-art scientific data on time of lineage divergence. This package constitutes the main underlying code of the DateLife web service at <https://www.datelife.org>. To obtain a single summary chronogram from a group of relevant chronograms, we implement the Super Distance Matrix (SDM) method described in Criscuolo et al. (2006) <doi:10.1080/10635150600969872>. To find the grove of chronograms with a sufficiently overlapping set of taxa for summarizing, we implement theorem 1.1. from Ané et al. (2009) <doi:10.1007/s00026-009-0017-x>. A given phylogenetic tree can be dated using time of lineage divergence data as secondary calibrations (with caution, see Schenk (2016) <doi:10.1371/journal.pone.0148228>). To obtain and apply secondary calibrations, the package implements the congruification method described in Eastman et al. (2013) <doi:10.1111/2041-210X.12051>. Tree dating can be performed with different methods including BLADJ (Webb et al. (2008) <doi:10.1093/bioinformatics/btn358>), PATHd8 (Britton et al. (2007) <doi:10.1080/10635150701613783>), mrBayes (Huelsenbeck and Ronquist (2001) <doi:10.1093/bioinformatics/17.8.754>), and treePL (Smith and O'Meara (2012) <doi:10.1093/bioinformatics/bts492>).

nichevol - Tools for Ecological Niche Evolution Assessment Considering Uncertainty

A collection of tools that allow users to perform critical steps in the process of assessing ecological niche evolution over phylogenies, with uncertainty incorporated explicitly in reconstructions. The method proposed here for ancestral reconstruction of ecological niches characterizes species' niches using a bin-based approach that incorporates uncertainty in estimations. Compared to other existing methods, the approaches presented here reduce risk of overestimation of amounts and rates of ecological niche evolution. The main analyses include: initial exploration of environmental data in occurrence records and accessible areas, preparation of data for phylogenetic analyses, executing comparative phylogenetic analyses of ecological niches, and plotting for interpretations. Details on the theoretical background and methods used can be found in: Owens et al. (2020) <doi:10.1002/ece3.6359>, Peterson et al.

Rogue - Identify Rogue Taxa in Sets of Phylogenetic Trees

Rogue ("wildcard") taxa are leaves with uncertain phylogenetic position. Their position may vary from tree to tree under inference methods that yield a tree set (e.g. bootstrapping, Bayesian tree searches, maximum parsimony). The presence of rogue taxa in a tree set can potentially remove all information from a consensus tree. The information content of a consensus tree - a function of its resolution and branch support values - can often be increased by removing rogue taxa. 'Rogue' provides an explicitly information-theoretic approach to rogue detection (Smith 2022) <doi:10.1093/sysbio/syab099>, and an interface to 'RogueNaRok' (Aberer et al. 2013) <doi:10.1093/sysbio/sys078>.

Tools for analysing, comparing, visualising and partitioning diversity based on Hill numbers. 'hilldiv' is an R package that provides a set of functions to assist analysis of diversity for diet reconstruction, microbial community profiling or more general ecosystem characterisation analyses based on Hill numbers, using OTU/ASV tables and associated phylogenetic trees as inputs. The package includes functions for (phylo)diversity measurement, (phylo)diversity profile plotting, (phylo)diversity comparison between samples and groups, (phylo)diversity partitioning and (dis)similarity measurement. All of these grounded in abundance-based and incidence-based Hill numbers. The statistical framework developed around Hill numbers encompasses many of the most broadly employed diversity (e.g. richness, Shannon index, Simpson index), phylogenetic diversity (e.g. Faith's PD, Allen's H, Rao's quadratic entropy) and dissimilarity (e.g. Sorensen index, Unifrac distances) metrics. This enables the most common analyses of diversity to be performed while grounded in a single statistical framework. The methods are described in Jost et al.

TreeSim - Simulating Phylogenetic Trees

Simulation methods for phylogenetic trees where (i) all tips are sampled at one time point or (ii) tips are sampled sequentially through time. (i) For sampling at one time point, simulations are performed under a constant rate birth-death process, conditioned on having a fixed number of final tips (sim.bd.taxa()), or a fixed age (sim.bd.age()), or a fixed age and number of tips (sim.bd.taxa.age()). When conditioning on the number of final tips, the method allows for shifts in rates and mass extinction events during the birth-death process (sim.rateshift.taxa()). The function sim.bd.age() (and sim.rateshift.taxa() without extinction) allow the speciation rate to change in a density-dependent way. The LTT plots of the simulations can be displayed using LTT.plot(), LTT.plot.gen() and LTT.average.root(). TreeSim further samples trees with n final tips from a set of trees generated by the common sampling algorithm stopping when a fixed number m>>n of tips is first reached (sim.gsa.taxa()). This latter method is appropriate for m-tip trees generated under a big class of models (details in the sim.gsa.taxa() man page). For incomplete phylogeny, the missing speciation events can be added through simulations (corsim()). (ii) sim.rateshifts.taxa() is generalized to sim.bdsky.stt() for serially sampled trees, where the trees are conditioned on either the number of sampled tips or the age. Furthermore, for a multitype-branching process with sequential sampling, trees on a fixed number of tips can be simulated using sim.bdtypes.stt.taxa(). This function further allows to simulate under epidemiological models with an exposed class. The function sim.genespeciestree() simulates coalescent gene trees within birth-death species trees, and sim.genetree() simulates coalescent gene trees.

extendedSurface - Fit Complex Multi-OU Models by Extending SURFACE and Providing an Interface with OUwie

Multi Ornstein Uhlenbeck (OUM) models are routinely employed to describe the phenotypic evolution of clades across a macroevolutionary adaptive landscape. Multiple implementations exist, including those that require an a priori assigment of lineages to adaptive regimes (e.g., OUwie), and those that infer the location of such regimes shifts (e.g., SURFACE). However, SURFACE has been found to favor overly complex models, which is likely a consequence of fixing a single rate of evolution and force of attraction for the entire tree. Although these parameters can be optimized for each regime by using the SURFACE output as the set of regime shifts required by OUwie, such complex models often fail to be optimized. extendedSurface provides a solution by continuing the backwards phase of SURFACE, merging regimes and generating simpler (yet suboptimal) multiOU models. These are then fed to OUwie, where parameters for each regime can be independetly optimized. Using simpler OUM models as starting points improves the probability of successful model fitting. The resulting models are more realistic, and have been found to be favored over others using empirical comparative datasets. The package allows the user to decide which models should be fit (OUMA, OUMV, OUMVA, with and without stationary root state), and plots the fit of these against those explored by SURFACE to easily compare model fit. Additionally, several approaches to record and plot the evolutionary dynamics of discrete traits through time are also implemented.

The main use case is to return a phylogenetic tree for a set of species, but the services also include ways to extract species names from web pages, perform taxonomic name resolution, retrieve a list of all descendant species of a taxon, find images of a species, and more.

CALANGO - Comparative Analysis with Annotation-Based Genomic Components

A first-principle, phylogeny-aware comparative genomics tool for investigating associations between terms used to annotate genomic components (e.g., Pfam IDs, Gene Ontology terms,) with quantitative or rank variables such as number of cell types, genome size, or density of specific genomic elements. See the project website for more information, documentation and examples, and <doi:10.1016/j.patter.2023.100728> for the full paper.

BMhyb - Comparative Methods for Phylogenetic Networks

Analyze the phenotypic evolution of species of hybrid origin on a phylogenetic network. This can detect a burst of variation at the formation of a hybrid as well as an increase or decrease in trait value at a hybridization event. Parameters are estimated by maximum likelihood, and model averaging can be done automatically. Users need to enter a comparative data set and a phylogenetic network.

closesamples - Gets feasible taxon samples on a tree

Often you want to pick species at random, but don't have access to all the possible species, and your group might be a nonrandom set. However, you might have a taxonomy, perhaps a bad one, for all the species. This will let you pick species at random on that full taxonomy and then pick a species out of the possible set closest to this. You could still have a biased sample, but way less biased.

flipped - Applies various odd models for coin flipping

Everyone uses the binomial as the distribution for coin flipping: this assumes for a given coin, the probability of landing heads is constant for all time. It is likely a very sound assumption. However, even for this simple example other models may be possible. This package contains such models.

popularitree - Subsamples a tree to get popular taxa

Often you want to show a reduced summary tree. Taxa chosen should span all the tree (for example, a tree of mammals should not have just primates) but also be recognizable groups to your audience. This lets you select a final tree size you want, criteria you want to use, and finds the tree that maximizes the criteria.

RateViz - Visualizations for instantaneous rate matrices

This package uses an instantaneous rate matrix (such as is used for models of DNA evolution, morphological character change over evolutionary history, and other areas) and summarizes it in various ways. These could include bubble plots, a network showing transitions, or calculations to figure out likely paths between two states.

TreePar - Estimating Birth and Death Rates Based on Phylogenies

(i) For a given species phylogeny on present day data which is calibrated to calendar-time, a method for estimating maximum likelihood speciation and extinction processes is provided. The method allows for non-constant rates. Rates may change (1) as a function of time, i.e. rate shifts at specified times or mass extinction events (likelihood implemented as LikShifts(), optimization as bd.shifts.optim() and visualized as bd.shifts.plot()) or (2) as a function of the number of species, i.e. density-dependence (likelihood implemented as LikDD() and optimization as bd.densdep.optim()) or (3) extinction rate may be a function of species age (likelihood implemented as LikAge() and optimization as bd.age.optim.matlab()). Note that the methods take into account the whole phylogeny, in particular it accounts for the "pull of the present" effect. (1-3) can take into account incomplete species sampling, as long as each species has the same probability of being sampled. For a given phylogeny on higher taxa (i.e. all but one species per taxa are missing), where the number of species is known within each higher taxa, speciation and extinction rates can be estimated under model (1) (implemented within LikShifts() and bd.shifts.optim() with groups !=0). (ii) For a given phylogeny with sequentially sampled tips, e.g. a virus phylogeny, rates can be estimated under a model where rates vary across time using bdsky.stt.optim() based on likelihood LikShiftsSTT() (extending LikShifts() and bd.shifts.optim()). Furthermore, rates may vary as a function of host types using LikTypesSTT() (multitype branching process extending functions in R package diversitree). This function can furthermore calculate the likelihood under an epidemiological model where infected individuals are first exposed and then infectious.

phybase - Basic functions for phylogenetic analysis

This package provides functions to read, write, manipulate, estimate, and summarize phylogenetic trees including species trees which contain not only the topology and branch lengths but also population sizes. The input/output functions can read tree files in which trees are presented in parenthetic format. The trees are read in as a string and then transformed to a matrix which describes the relationship of nodes and branch lengths. The nodes matrix provides an easy access for developers to further manipulate the tree, while the tree string provides interface with other phylogenetic R packages such as "ape". The input/output functions can also be used to change the format of tree files between NEXUS and PHYLIP. Some basic functions have already been established in the package for manipulating trees such as deleting and swapping nodes, rooting and unrooting trees, changing the root of the tree. The package also includes functions such as "consensus", "coaltime, "popsize", "treedist" for summarizing phylogenetic trees, calculating the coalescence time, population size, and tree distance. The function maxtree is built in the package to esimtate the species tree from multiple gene trees.
