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, 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, 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.
