A Getting the software

A.1 Pre-requisites

This book uses an R package, dfstools. You will need the following pre-requisites:

1. R: 3.5.1 or later. Technically, any R version 3.5.0 should work, but I only can support the most recent version.
2. RStudio: Version 1.2.1186 or later. This is currently a preview release (2018-12-17) but is stable enough for daily use.
3. Git: version 2.20 or later.

A.2 Installing dfstools

1. Open RStudio.
2. In the R console, type update.packages().
3. If you haven’t installed devtools yet, install it with install.packages("devtools").
4. devtools::install_github("znmeb/dfstools", force = TRUE, build_vignettes = TRUE, quiet = TRUE).

A.3 dfstools documentation

dfstools has a pkgdown site at https://znmeb.github.io/dfstools. You’ll also have this documentation available in RStudio after you install dfstools.

Please feel free to open an issue at https://github.com/znmeb/dfstools/issues/new/choose if you have any problems with dfstools or want to request a feature.
