DSUR

This contains codes and data I’ve used while learning multivariate data analysis with Andy Field’s Discovering Statistics Using R (DSUR) excellent book. All of the codes to Andy’s book can be found here.

As was said, codes to the book are already freely available. This is not a copy of the book or its scripts. Although most codes used came from the book:

• Packages that are already in disuse were here updated (example: WRS was updated to WRS2).
• tidyverse syntaxes are employed.
• S4 syntaxes are employed.
• Code is uniformly formatted (examples: data.frame object in use is generally referred as df, robust tests are separated from non-robust procedures).
• Syntaxes' organization is different to facilitate my own understanding. This means that subjects are treated in the order I better see fit.

Most of the time, especially in the later chapters, direct quotations from the book are shown. They’re easily recognizable due to their size and the #' notation. This is used to preserve Andy’s interpretation of the results.

Furthermore, this repo has the following structure:

• Data Files: this folder contains all of (or most of) the data files used in Andy Field’s book. The whole list of data files, by chapters, can be found here. What I’ve done is put the ones I use in the syntaxes in this one folder.

• Scripts: syntaxes by chapter. Some chapters are divided in more than one part to aid my own understanding of the code. All scripts I deemed useful and/or relevant were put here. Just as before, and as already mentioned, DSUR’s site already has script files divided by chapter: they can be found here. The ones used here were not copied from these scripts and are in fact very different from those.

Below is a plot made for the final chapter of the book. Hope this helps!
