data.tree v0.7.0
General Purpose Hierarchical Data Structure
Create tree structures from hierarchical data, and traverse the
tree in various orders. Aggregate, cumulate, print, plot, convert to and from
data.frame and more. Useful for decision trees, machine learning, finance,
conversion from and to JSON, and many other applications.

data.tree
An R package to manage hierarchical data and tree structures
Hierarchical data is ubiquitous in statistics and programming (XML, search trees, family trees, classification, file system, etc.). However, no general-use tree data structure is available in base R. Where tabular data has data.frame, hierarchical data is often modeled in lists of lists or similar makeshifts. These structures are often difficult to manage. This is where the data.tree package steps in. It lets you build trees of hierarchical data for various uses: to print, plot and visualize, to generate breakdowns, to integrate with html widgets, to rapid prototype search algorithms, to test out new classification ideas, and much more.
Tree structures can be created programmatically, or by conversion. The package provides functionality to convert from and to various formats such as data.frames, list of lists, dendrograms, partykit, ape phylo, igraph, JSON, YAML, and more.
