Course overview

Although there are many datasets available in convenient formats, there’s also a lot of data that’s more difficult to access, like a table on a web page. To get this data, we’ll need to use web scraping. In R, we can do that with the rvest scraping package.

In this course, you’ll learn about web page structure, including the basics of HTML and CSS. You’ll also learn how to get the code from a page into your R workflow for further parsing and cleaning. Then, you’ll dig deeper into scraping, learning to use the CSS Selector to get precisely the data you want.

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 complete a guided project that asks you to use web scraping to analyze movie ratings.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
