Learn R Programming

⚠️There's a newer version (2.4.0) of this package.Take me there.

openintro

Supplemental functions and data for ‘OpenIntro’ resources, which includes open-source textbooks and resources for introductory statistics at openintro.org. The package contains data sets used in our open-source textbooks along with custom plotting functions for reproducing book figures. The package also contains the datasets used in OpenIntro labs. Note that many functions and examples include color transparency; some plotting elements may not show up properly (or at all) when run in some versions of Windows operating system.

Installation

You can install the released version of openintro from CRAN with:

install.packages("openintro")

You can install the development version of openintro from GitHub with:

# install.packages("devtools")
library(devtools)
install_github("OpenIntroStat/openintro")

This package was produced as part of the OpenIntro project. For the accompanying textbook, visit openintro.org. A PDF of the textbook is free and paperbacks can be purchased online (royalty-free).

Questions, bugs, feature requests

You can file an issue to get help, report a bug, or make a feature request.

When filing an issue to get help or report a bug, please make a minimal reproducible example using the reprex package. If you haven’t heard of or used reprex before, you’re in for a treat! Seriously, reprex will make all of your R-question-asking endeavors easier (which is a pretty insane ROI for the five to ten minutes it’ll take you to learn what it’s all about). For additional reprex pointers, check out the Get help! section of the tidyverse site.

Before opening a new issue, be sure to search issues and pull requests to make sure the bug hasn’t been reported and/or already fixed in the development version. By default, the search will be pre-populated with is:issue is:open. You can edit the qualifiers (e.g. is:pr, is:closed) as needed. For example, you’d simply remove is:open to search all issues in the repo, open or closed.

Code of Conduct

Please note that the openintro project is released with a Contributor Code of Conduct. By contributing to this project, you agree to abide by its terms.
