Defensive R Programming

In this first chapter, you'll learn what defensive programming is, and how to use existing packages for increased efficiency. You will then learn to manage the packages loaded in your environment and the potential conflicts that may arise.

Programming is simpler when you get feedback on your code execution. In R, we use messages, warnings and errors to signal to keep the user informed. This chapter will discuss when and where you should use these communication tools.

We can avoid making mistakes using a consistent programming approach. In this chapter, we will introduce you to R best practices.

Creating a script is nice, but working on a project with several scripts and assets requires structure. This final chapter will teach you good organization practices, so you can go from script to package with an optimal workflow.
