Tree is a recursive directory listing command that produces a depth indented listing of files, which is colorized ala dircolors if the LS_COLORS environment variable is set and output is to tty.

This package provides procedures to work with classification and regression trees.

The treecc program is designed to assist in the development of compilers and other language-based tools. It manages the generation of code to handle abstract syntax trees and operations upon the trees.

This package provides software for phylogenomic inference.

This application provides a way to unify the formatting process of the codebase. It is nice for large code trees where using multiple formatters are common. treefmt comes with the following features.

• Unified CLI and output.

• Runs formatters in parallel.

• Cache changed files for performance.

The application does have some design decisions to keep in mind.

• The source code is kept under version control, making it possible to revert and check changes.

• Only one formatter per file, making outputs idempotent.

This package implements binary trees of various kinds, presenting a uniform interface to them all.

This is an R package to make it easier to import and store phylogenetic trees with associated data; and to link external data from different sources to phylogeny. It also supports exporting phylogenetic trees with heterogeneous associated data to a single tree file and can be served as a platform for merging tree with associated data and converting file formats.

This package implements binary trees of various kinds, presenting a uniform interface to them all.

A treemap is a space-filling visualization of hierarchical structures. This package offers great flexibility to draw treemaps.

treekoR is a novel framework that aims to utilise the hierarchical nature of single cell cytometry data to find robust and interpretable associations between cell subsets and patient clinical end points. These associations are aimed to recapitulate the nested proportions prevalent in workflows inovlving manual gating, which are often overlooked in workflows using automatic clustering to identify cell populations. We developed treekoR to: Derive a hierarchical tree structure of cell clusters; quantify a cell types as a proportion relative to all cells in a sample (%total), and, as the proportion relative to a parent population (%parent); perform significance testing using the calculated proportions; and provide an interactive html visualisation to help highlight key results.

This package implements binary trees of various kinds, presenting a uniform interface to them all.

This package provides tools to create a measure of inter-point dissimilarity useful for clustering mixed data, and, optionally, perform the clustering.

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

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. This is useful for decision trees, machine learning, finance, conversion from and to JSON, and many other applications.

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

Tree-sitter aims to be:

• General enough to parse any programming language

• Fast enough to parse on every keystroke in a text editor

• Robust enough to provide useful results even in the presence of syntax errors

• Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application

This package includes the libtree-sitter runtime library.

Generic tools for recursive and iterative tree traversal based on clojure.walk and clojure.zip respectively.

This package provides a Ruby-based Parsing Expression Grammar (PEG) parser generator Domain Specific Language (DSL).

The arrangement of hypotheses in a hierarchical structure appears in many research fields and often indicates different resolutions at which data can be viewed. This raises the question of which resolution level the signal should best be interpreted on. treeclimbR provides a flexible method to select optimal resolution levels (potentially different levels in different parts of the tree), rather than cutting the tree at an arbitrary level. treeclimbR uses a tuning parameter to generate candidate resolutions and from these selects the optimal one.

A tree utility library

This package provides a C grammar for the Tree-sitter library.

This package provides a R grammar for the Tree-sitter library.

The TreeAndLeaf package combines unrooted and force-directed graph algorithms in order to layout binary trees, aiming to represent multiple layers of information onto dendrogram leaves.

This Haskell library provides a function for computing the difference between (expression) trees. It also provides a way to compute the difference between arbitrary abstract datatypes (ADTs) using Generics-derivable helpers.
