ggspec

Extract and Compare 'ggplot2' Plot Specifications as Tidy Data Frames

v0.1.0 · May 28, 2026 · MIT + file LICENSE

Description

Inspects 'ggplot' objects by extracting their full declarative specification - layers, aesthetic mappings, scales, facets, coordinate systems, and labels - as tidy data frames. A second tier of functions enables structural comparison of two 'ggplot' objects, supporting automated plot testing, auditing, and framework-agnostic grading workflows. Unlike 'ggcheck', which is designed exclusively for 'learnr'/'gradethis' pipelines and returns ad-hoc objects, 'ggspec' returns rectangular, pipeable output and does not require any grading framework as a dependency.
