Unit 3

In this unit, you’ll bundle your code from the quarter so far into a formal R package that will streamline and document your data collection, cleaning, and analysis. We’ll start with some simple example R packages, to learn what makes something a true package, and what tools exist to help you out in the development workflow.

Then, we will dig deeper into good code development practices. You’ll learn to write good, through unit tests for your functions, both in and out of the package formal. Then we’ll revisit debugging and introduce more strategies for finding problems in your code.

Finally, you’ll think more deeply about the speed and memory demands of the code you write. We’ll learn about benchmarking to find out where in your code a slowdown occurs, and we’ll learn a few very modern packages and coding techniques for faster code.
