Johns Hopkins R Programming Course introduces SWIRL

When reviewing Coursera’s excellent Johns Hopkins R Programming course this evening delivered by Roger D. Peng it introduced me to swirl.

What I hear you ask is swirl? Well it is an interactive R tutorial which can be run from R or R Studio.

Previously I’ve been getting my students to run the Try R interactive tutorial from codeschool but I think from now on it will be swirl.

To enter into the swirl interactive R tutorial – open up R or R Studio and type the following and enjoy the hours spent practicing R:

I must say I am really impressed with this course and it only costs $43 per month – I managed to get through the first 3 weeks of lectures, quizzes, and practicals this evening. This is the second of nine courses in this specialisation. I am so impressed that I bought Professor Peng’s books, course notes, videos, datasets. If there were t-shirts, I would have bought one too.
