ggtree: visualization and annotation of phylogenetic trees

The ggtree package extending the ggplot2 package. It based on grammar of graphics and takes all the good parts of ggplot2. ggtree is designed for not only viewing phylogenetic tree but also displaying annotation data on the tree. ggtree is released within the Bioconductor project and the source code is hosted on GitHub.

Overview

Getting tree into R

  • tree parsers: bring evolution evidences to be used/analyzed in R
  • merge_tree: allows evolution evidences to be merged and compared
  • fortify methods: convert tree objects into tidy data frame

Tree visualization & annotation

  • parsing tree as a collection of nodes allows grammar of graphics to be supported
  • geom_tree: extends ggplot2 to support tree structure
  • several layers and functions for tree annotation
  • supports annotating phylogenetic trees with user’s own data

Tree manipulation

  • helper functions for tree manipulation, make it possible to explore the tree visually
