Good resources for learning R from scratch
From my experience:
- Code School: Try R on http://tryr.codeschool.com/
Step by step instruction on a web based R environment (meaning you don’t need to install R and thus can work on any computer that is available to you). Very easy (and slow) at first.
However, this website seems to require a physical keyboard to type the code and numbers in. I couldn’t learn using my tablet.
- Swirl: http://swirlstats.com/
I prefer this one to Code School. There are lessons in various topics, from basic to intermediate that corresponds to the similar courses in Coursera, including R Programming, Data Analysis, Getting and Cleaning Data, and Regression Models. The lessons are faster (and less boring) at first. All you need to do is installing R and RStudio yourself and run swirl package. You need to practice on the real R/RStudio, which gets you quickly familiar with the real R working environment.
