This website is a directory for free and open source swirl courses. If you’re completely new to R you should read this page first which will help you install R, RStudio, and swirl. If you’re set up with R and you’re looking for more swirl courses you can browse available courses by the name of the course or by the name of the author of the course. Click “Browse Courses” above to start browsing! If you’re looking for a course to start with we recommend the R Programming course.
