Daily air quality is measured by the air quality index (AQI) reported by the
Environmental Protection Agency.

Supplemental functions and data for 'OpenIntro' resources, which
includes open-source textbooks and resources for introductory statistics
(<https://www.openintro.org/>). The package contains data sets used in our
open-source textbooks along with custom plotting functions for reproducing
book figures. 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.
