  • New functions to measure cluster sizes (see ?"cluster-statistics").

  • KMeansPP() conducts clustering using K-means++, replacing K-means in app.

  • New vignette on tree landscape analysis.

TreeDist 2.4.1 (2022-07-20)

  • New vignette on how to compare tree sets.

  • PathVector() now treats trees with a root node as rooted.

  • Fix plot layout in treespace vignette.

  • Solaris compatibility.

  • Modest vignette improvements.

  • spic/scic abbreviation recognition.

TreeDist 2.1.0 (2021-07-12)

New features

  • ConsensusInfo() quickly calculates the splitwise information content of the consensus of a set of trees, after Smith (forthcoming).

  • SplitwiseInfo() and ClusteringInfo() gain a p parameter to reflect the reduced information content of splits with lower support values, and a sum parameter to allow return of individual split information content.

  • KCDiameter() approximates the diameter of the Kendall-Colijn metric.

  • Plot3() (experimental) provides pseudo-3D plotting.

Renamed functions

  • Project()/ProjectionQuality() re-named to MapTrees()/MappingQuality().

  • SpectralClustering() re-named to SpectralEigens().

Improvements

  • Add self-organizing map example to treespace vignette.

  • Allow the specification of custom vectors in the Kendall--Colijn metric.

  • Faster all-to-all tree distance calculation.

TreeDist 2.0.3 (2021-01-31)

  • Diagnose and fix memory leaks, including over-long reported matchings.

  • Explicitly import shiny/shinyjs functions.

  • Project() launches 'shiny' app for projection and analysis of tree space.

  • ProjectionQuality() calculates trustworthiness and continuity of tree space mappings.

  • Faster calculation of Robinson–Foulds distance (using algorithm of Day (1985)) and clustering information distance.

  • New class ClusterTable to allow faster distance computation with Day (1985) algorithm.

  • Improve error messages in CalculateTreeDist().

  • Improve floating-point arithmetic in TreeDistance() functions.

  • TreeDistance() now returns a distance (as documented), rather than a similarity.

  • Fix rounding error in NNI 'Li' upper estimate, and improve NNI performance.

  • Reduce precision of LAPJV so rounding errors do not result in interminable run times.

TreeDist 1.1.1 (2020-07-10)
