phylopath 1.3.1

• Maintenance update to confirm to update CRAN documentation guidelines.

phylopath 1.3.0

• MuMIn was removed as a dependency, as it was threatened to be removed from CRAN.

phylopath 1.2.1

• A warning is now generated when a user passes a data column with binary data as a numeric vector.
• Informative errors are now returned when the orderargument does not contain each variable exactly once.
• Fixed a rare bug in find_consensus_order, due to a particular edge case of order combinations. In old R versions this would generate a warning about the an if condition with length > 1, which in newer versions results in an error. (Thanks to Laura Alencar for the report.)

phylopath 1.2.0

• Replaced parallel processing based on the parallelpackage and pbapply to use future instead. Use e.g. future::plan("multisession", workers = n) to enable parallel processing for both model comparison (parallel over dsep statements) and model estimation (when using bootstrapping).
• Fixed a bug that no longer allowed parallel processing inphylo_path.
• Fixed a bug where the range of the width scale for paths inplot.fitted_DAG was incorrectly set to themax(weight), instead of max(abs(weight)). (Thanks Yu Xu for the report.)
• Better user messaging and documentation around the use of theboot parameter.
• Update of binary vignette to include more info on convergence warnings.

phylopath 1.1.3

• Fixed a bug that made phylo_path fail to pass additional (…) arguments correctly to phylolm.
• Add informative error when trying to plot a DAG without any paths.
• Updated plotting functions to work with new ggraphreleases.
• Fixed regression with parallel usage of phylo_pathdue to an S3 inheritance issue on the cluster (#16, thanks Simon Greenhill for the report).

phylopath 1.1.2

• Prepare for R v4.0.0.
• Bug fix: Very low p-values could cause underflow and result in infinite C statistics. All p-values are now set to be at least the size of the machine accuracy (i.e. 2 * 10^-16).
• Warnings are now again correctly reported.

phylopath 1.1.1

• Prepared for next release of ggraph.

phylopath 1.1.0

• Bug fix: It was possible to get CICc values in the summary output that were not valid. Specifically, to calculate CICc there is a division by (n - 1 - q), where n is the number of observations (species) and q the number of parameters in the causal model. This could lead to infinite CICc whenn == q + 1, or a flipped of CICc whenn < q + 1. This would typically only occur when attempting to fit models with very few species (e.g. < 10).
  New behavior is to set CICc to NA when n is insufficient, and to give a warning.
• Removed dependencies dplyr and tidyr, but added tibble.

phylopath 1.0.2

• Prepare for dplyr 0.8.0 release.

phylopath 1.0.1

• Fixed bug that would return the wrong model in some error messages.
• Improved reporting of warnings, and ashow_warnings() function has been added.
• Citation info now points to the PeerJ paper.

phylopath 1.0.0

• Citation info now points to the bioRxiv paper.
• All modeling functions now completely rely on thephylolm package, and no longer use ape. This is a major change, that will possibly change the outcomes of some of your existing analyses (as can happen when chaning the modeling package). There are, however, several good reasons to make this change, which I think make it worth the trouble. Firstly, the package is much faster for large trees, and this effect is compounded inphylopath because one may have to fit a few dozen models. Secondly, I think it is important to have confidence intervals around the regression coefficients, and those were not available forape::binaryPGLMM. Thirdly, phylolm makes it easy to use a larger variety of models of evolution, including two versions of OU and early burst, which can be simply set using themodel parameter. Lastly, the phylolm() andphyloglm() functions give more uniform results, which makes it easier to code for situation where you may use both.
• phylo_path and all related methods now deal automatically with both continuous and binary data. All separate binary functions and methods have disappeared as they are no longer needed. Mixing of binary and continious data in the same models is now allowed.
• The variable order in d-seperation statements now better follows the causal flow of the DAG.
• Added plot() method forphylopath.summary objects, that shows the weights and p-values for the different models.
• coef_plot() gained error_bar,order_by, from and to arguments. The first allows the user to choose between confidence invervals and standard errors, the second to order the paths by several methods, and the last two can be used to select only certain paths.
• Plotting methods of causal models now support a manual layout.
• Plotting of fitted DAG’s now uses edge width instead of color to indicate, the standardized regression coefficient strength, but this can be reverted using the type argument.
• Added a define_model_set() convenience function for building models, that avoids repeated calls to DAG() and has an argument to supply paths that are shared between all your models. It is not needed to specify isolate variables. Old code usingDAG() continues to work as normal.
• Added support for additional arguments passed to glsfrom phylo_path. This can be helpful, for example, for setting the fitting method to maximum likelihood (method = "ML").

phylopath 0.3.1

####Bugfixes:

• The package broke due to an update of purrr, but has now been fixed (reported by Christoph Liedtke, @hcliedtke).
• The package depends on a recent version of nlme, but this wasn’t specified. All package versions of dependencies are now defined (reported by @ManuelaGonzalez).

phylopath 0.3.0

• Added support for completely binary models, that are fitted withape::binaryPGLMM. Use phylo_path_binary() to compare models. average(), best() andchoice() are now S3 generics and will handle both continuous and binary versions. Usage is designed to be as close to the continuous version as possible. est_DAG_binary() powers the binary S3 methods.
• All plot functions that used DiagrammeR now useggraph instead. This gives much more control over the positioning of the nodes, and allows to plot multiple models at once. Exporting plots also becomes much easier.
• You can now plot a list of causal models withplot_model_set(). This creates a faceted plot where all nodes are kept in the same location, which makes it easier to spot how models are different.

phylopath 0.2.3

• If there are any NA values in data for the variables in models, these rows are now dropped fromdata with a message. Use na.rm = FALSE to revert to the old behavior.
• When PGLS models fail, an informative error is now returned to the user.
• phylo_path() now checks for row.names that line up with the tree tip labels. If the tree contains surplus species, it gets pruned to size with a message. This includes cases where species are dropped due to missing values.
• citation() now correctly refers to the methods paper by Von Hardenberg & Gonzalez-Voyer first and the package second.

phylopath 0.2.2

• Fewer models are now fitted when using phylo_path(), since any duplicated independence statements are now only fitted once. This leads to a significant reduction in running time in many cases, especially when many models are considered.
• Implemented support for parallel processing inphylo_path() using the parallelargument.
• phylo_path() now shows a progress bar.
• New function added (choice()) that is a very simple wrapper around est_DAG(). It adds to best()and average() by allowing for choosing any model as the final model, and encourages users to not always pick the lowest CICc model.
• Prepared plotting functions for new release ofDiagrammeR, v0.9 now required.

phylopath 0.2.1

• IMPORTANT: Faulty model averaging has been fixed. This was often introduced due to differences in matrix ordering. Averaging results from versions before 0.2.1 should NOT be trusted.
• Using ape::corBrownian() no longer returns an error.
• Averaging is less likely to fail due to errors innlme::intervals().

phylopath 0.2.0

• phylo_path() has become more streamlined with functionality moved to other functions. The phylopathobject now contains all necessary models and data,summary() is used to obtain the results table, andbest() and average() are used to extract and fit the best or average model. See the vignette for details.
• Model averaging for arbitrary models is now possible withaverage_DAGs().
• Model averaging now supports both conditional and full model averaging.
• Both the old est_DAG() and the newaverage_DAGs() now return objects of a new classfitted_DAG, that has it’s separate plotmethod. The plot method for objects of classDAG has been simplified.
• Model averaging now returns standard errors and confidence intervals based on the MuMIn package (issue #1).
• A new function plot_coefs for plotting regression coefficients and their confidence intervals has been added.
