In this appendix, I will show you how to install the software you need to replicate the examples shown in this book. I will show you how to do so for Linux and macOS, specifically, Ubuntu 17.10 and High Sierra. If you're using Windows, the same principles apply but the specifics may be a bit different. However, I'm sure it will not be too difficult in any case.
There are two types of requirements for executing all the code in this book: external and internal. Software outside of R, is what I call external requirements. Software inside of R, meaning R packages, are what I refer to as internal requirements. I will walk you through the installation of both of these.
