In this course, you’ll begin by learning control flow (including if-else statements) and conditionals. You’ll then move into learning about functions and functional programming. You’ll also learn about iteration, how to write for loops and while loops, and when and why you might choose to write a for loop instead of employing vectorization in R.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you’ll work on the first part of a guided project that will enable you to apply control flow loops and functions to create a reusable data workflow.
For this project, you’ll act as a data analyst for a company selling programming books to analyze sales data and extract useful insights to determine the most profitable titles.
