stringsAsFactors=FALSE as default. For backwards compatibility, stringsAsFactors is set to TRUE internally to mimic the previous default behavior. For the time being, conversion to non-factors data types will need to be handled manually.ancestors() function to remove unused ....Initial basic support for converting RNeXML objects in phylo4 and phylo4d format.
New methods: internalEdges(), terminalEdges()
descendants() has now a "ALL" argument to include self in results
New method: nodeHeight() provides a consistent and comprehensive way of calculating the distance between a node and either the root or the tips. (fix #3)
The replacement methods for labels, tipLabels, nodeLabels, edgeLabels now accept NA or NULL to remove labels (fix #2)
readNexus and readNewick now internally use the package rncl to parse files. They also use a different approach to reconstruct the edge matrix. These changes make file parsing faster. Objects created with this new approach may not exactly be identical to those created in previous versions as node numbering might differ, they should however be fully compatible with each others.
readNexus and readNewick can now parse tree files with trees containing a subset of the taxa listed in the TAXA Block.
Source code for the package is hosted on GitHub at https://github.com/fmichonneau/phylobase
All tests done with testthat
rootNode returns the rootNode using the same format as getNode().
All documentation is in Roxygen format
hasPoly, hasRetic, hasSingle are now methods instead of functions.
nodeDepth and depthTips are now deprecated and are replaced by nodeHeightFix bug: NA in labels were considered duplicated by checkPhylo4().
Fix bug #605 (R-forge) – treePlot subsets numeric data for plotting.
Fix bug #4: descendants() behave like ancestors() when provided with a vector of nodes and is consistent across all arguments.
Not many user-visible changes, most are related to improving speeds during test of object validation (most tests done in C++) and to getNode that is used by many functions.
Changes to package structure to make it compatible with devtools (switching testing to testthat – partial at this stage) and docs to roxygen format (partial at this stage).
Changes to package structure to comply with new Rcpp standards
Updates from cout/cerr to Rcpp::Rcout/Rcerr
Comments in Nexus tree strings are being removed before being processed by readNCL
Fixed bugs in getNode in cases where labels included regexpr metacharacters and when a tip was labelled 0
New methods: depthTips, nodeDepth and isUltrametric
Improve handling of errors returned by NCL (NxsException)
Fix bug in case state labels are missing from the NEXUS file
Upgrade to NCL 2.1.14
Updated to the Nexus Class Library (NCL) 2.1.12.
Changed the way NCL is built during the installation process.
Complete rewrite of the function readNexus which brings many new functionalities.
Nodes labels do not have to be unique.
In readNexus, the option return.labels gives the state labels of the characters.
It is now possible to import several types of data blocks in a single NEXUS file with readNexus.
The function phylobase.options() provides global options to control the behavior of the phylo4/phylo4d validator.
The new method hasDuplicatedLabels() indicates whether any node labels are duplicated.
The new method nData() returns the number of datasets associated with a tree.
The column that contains the labels can now be specified by its name in the function formatData()
The function getNode() has been modified to allow node matching in the case of non-unique labels.
Many new unit tests.
Unrooted trees are not supported by all functions, e.g. plot() and reorder().
Factors are not supported by the default plotting method.
A var-cov matrix tree class, phylo4vcov, and methods for converting to and from other classes now exists.
Replaced separate the tip.label and node.label slots with a unified label slot in the phylo4 class definition.
Replaced separate the tip.data and node.data into a single data slot in the phylo4d class definition.
The phylo4 class grew a annotate slot.
The phylo4d class grew a metadata slot.
Added an order slot to the phylo4 class definition and updated as() methods to assign the proper order (if possible) when converting between ape and phylobase tree formats.
The Nnode slot was removed from the phylo4 class definition.
An explicit root edge has been added to the edge matrix with 0 as the ancestor and nTips(phy) + 1 as the rood node.
The edgeLabels() and edgeLength() accessors now return vectors with named elements in the same order as rows of the edge matrix, even when some/all values are missing.
The labels() accessor and nodeID() methods now always return labels in ascending order of node ID
Many function and argument names and defaults have been changed to make them more consistent most functions follow the getNode() pattern.
The plotting functions have been replaced (see below).
Now, data are matched against node numbers instead of node labels.
Tip and internal node labels have now internal names that are character strings of the node number they correspond to. Thus it is possible to store labels in any order and assignment of labels more robust.
We now use the RUnit package (not required for normal use) for adding unit tests. Adding unit tests to inst/unitTests/ is now preferred over the tests/ directory.
Numerous changes to pruning and tree subsetting code. It is considerably more robust and no longer relies on calls to APE.
Added a function nodeType() for identifying whether a node is root, tip or internal.
Changed nodeNumbers to nodeId() and extended it abilities.
Added method reorder() for converting edge matrices into preorder or postorder.
Added the edgeOrder accessor to get the order of a phylobase object.
Added a package help file accessible from ?phylobase.
Added labels()<- for assigning labels.
Added edgeLength()<- for assigning edgeLengths.
Added a phylo4() method for importing APE phylo objects.
Added a hasTipData() method.
Added a edgeId() method.
Created the addData() method for adding data to phylo4 objects.
Added tipData and nodeData getter/setter methods
If all node.labels are numerical values, they are automatically converted as data. Useful when importing consensus tree from MrBayes.
It is now possible to print tree objects in edge order using the edgeOrder argument in printphylo4().
reorder(), descendants(), ancestors(), and portions of the plotting code have been recoded in C to improve performance.
Added a developer vignette to document and guide development of the phylobase package.
The previous plotting functions, based on base graphics, have been replaced with function based on the grid graphics device.
A S4 generic plot() function, calling treePlot() has been added it dispatches a plotting function based on object class and arguments.
Plots using grid based code can be inserted at the tree tips using the tip.plot.fun argument in plot()
The getNode() method has been enhanced to allow matching against specific node types, and if the requested node is missing, all nodes of specified type are returned.
Changed getEdge() to allow no node argument, which returns all edges appropriate for the given type.
Node labels are, if not supplied, a vector of NA.
printphylo() is now deprecated, print() and summary() now alsow work on empty objects.
phylo4() is now and S4 generic with signature “matrix”.
phylobase now uses a NAMESPACE file.
Legacy plotting code (0.4) can be found in the SVN repo tags directory.
The tdata default “type” argument changed to ‘all’.
Row names now stored internally as numeric, not character.
Unrooted trees are not supported by all functions, e.g. plot() and reorder().
Factors are not supported by the default plotting method.
The Nexus Class Library is build for the system default ARCH which may or may not be the architecture that R and the rest of the package is built with. If this occurs the package will fail to load.
Unique labels are required for internal nodes, this behavior will be changed in the future.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
