To get the most out of this book

No previous experience with R, Shiny, HTML, or CSS is required to use this book, although you should possess some previous experience with programming in a different language. This book can be used with the Windows, macOS, or Linux operating systems. It requires the installation of R as well as several user-contributed packages within R. R and its associated packages are all available for free. The RStudio IDE is recommended because it simplifies some of the tasks covered in this book, but is not essential. Again, this software is available free of charge.
