How this book was made

This book was made using R (R Core Team 2018), and the bookdown package (Xie 2016), which is based on Markdown syntax, using knitr (Xie 2015).

Numerous other R packages were used too:

• The display of some data tables in the online version use the DT package (Xie, Cheng, and Tan 2018).
• The NHANES data is provided by the NHANES package (Pruim 2015).

All of this software is free and open source.

Other resources used include:

• The quizzes are embedded using H5P iframes.
• Icons are from iconmonstr and are freely available.
