Like Moazzem Hossen, I don't have any formal education in programming or statistics, however I do have a bit of experience (I definitely don't consider myself a developer though) in a few programming languages. I have been considering doing the coursera program, but I've also found some reasonably-priced courses on Udemy as well that focus solely on R and are put together well for people who are starting from zero.
Personally, I find the way lesson plans are put together really affect how effectively I learn, so a good teacher is important. I'm not affiliated with this guy at all, but I'm taking this course right now and I like his teaching style and have taken his courses on other topics as well. Good luck!
