I can't think of one single thing that would make a better interactive course, the format is truly exceptional. It shows Code School have some of the best usability experts in the world on board. I would rate this 5 if it included more advanced topics as well. I'm hoping for a follow-up!

Great job to the Code School folks who put this interactive tutorial together. I've used "intro to R" books and videos but this was my favorite. Whenever someone has a couple free hours and is serious about finally learning R for the first time, this tutorial is perfectly designed and fun to use.

It took me about an hour, but I it was very pleasure experience. Examples was great and even with so short course I was able to fill the power of R. Looking forward to try more courses. Keep it rolling! Nice job, guys!

Very nice and smooth transition into the R language. I have always been hearing about it, but never made the move to try it until now. I love technology, especially when it comes on to programming and the dynamics these languages have to offer. This is a very good addition to my programming toolkit; everyone should give it a try. Keep up the excellent work Code School!
