## 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 diagrams were made in base
**R**, or using the**diagram**package (Soetaert 2017). - The animations in the html version were made using the
**animation**package (Xie 2013), and the stills for the PDF version captured by the**webshot**package (Chang 2018). - The
**gifski**package was used to create animations in the online version (Ooms 2018). - The
**kableExtra**package was used for nicer tables (Zhu 2018). - The maps of Australia were generated using the
**oz**package (Venables and Hornik 2016) and plotted using the**ggplot2**package (Wickham 2016). - The display of some data tables in the online version use the
**DT**package (Xie et al. 2018). - Some plots use the
**plotrix**package (Lemon 2006). - The NHANES data is provided by the
**NHANES**package (Pruim 2015). - Some data are from the
**GLMsData**package (Dunn and Smyth 2017). - The
**scales**package is used to rescale data (Wickham 2018). - The carousels in the online version (for example, Sect. 33.3) are made using the
**slickR**package (Sidi 2018). - The
**dygraphs**package (Vanderkam et al. 2018) is used to make interactive graphs (for example, Sect. 12.8.4) for the online version. - The
**plotly**package (Sievert 2018) is used to make some interactive graphs (for example, in Sect. 12.2.3) for the online version. - The
**dplyr**package is used in some data manipulations (Wickham et al. 2019). - The
**viridis**package is used for some colour specifications (Garnier 2018) to make colours easier for those with colour-blindess to distinguish colours, and for better greyscale printing. - The
**webex**package was used to create the interactive web exercises (Barr and DeBruine 2019). - The
**plotfunctions**package was used to add images to existing plots (van Rij 2020)

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. - The images of the cards used in Sect. 15.2 are from https://code.google.com/archive/p/vector-playing-cards/, and are in the public domain.
- The text folding (in the html version) was implemented by adapting advice from StackOverflow.
- The images of dice used in, for example, Sect. 16.2, are from https://www.clipartkey.com/, and are free.
- The cover for the book was made using a free image using Canva.
- The images used in the online book are free (and used according to their guidelines), as listed in Appendix F.
