Overview

About

Maintained by Christopher T. KennyFirst published 2026-02-201 releasesCRAN page ↗GitHub ↗

Provides an S3 class to represent graph adjacency lists using 'vctrs'. Allows for creation, subsetting, combining, and pretty printing of these lists. Adjacency lists can be easily converted to zero-indexed lists, which allows for easy passing of objects to low-level languages for processing.
