## Overview

{dataedu} is an R companion package for *Data Science in Education Using R*. Its main user workflow is to load the package, then access walkthrough datasets by name; users can also install the book’s package set and reuse the package’s theme and color palette. The repository additionally ships datasets in CSV/JSON form under inst/extdata. No source excerpts were provided, so relationships below rely on README statements; internal calls and implementation details are not inferred.

Main entry points: [`R/dataedu-package.R`](https://github.com/data-edu/dataedu/blob/master/R/dataedu-package.R) (dataedu package), [`data`](https://github.com/data-edu/dataedu/tree/master/data) (Walkthrough datasets), [`inst/extdata`](https://github.com/data-edu/dataedu/tree/master/inst/extdata) (CSV and JSON exports), [`R/install_dataedu.R`](https://github.com/data-edu/dataedu/blob/master/R/install_dataedu.R) (Package installer)
