⚠️There's a newer version (1.1.0) of this package.Take me there.

data.tree (version 1.0.0)

General Purpose Hierarchical Data Structure

Description

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.
