Free online courses in stat and data mining - Coursera

I discovered by chance a website that I thought was absolutely wonderful, with sensational and free courses taught by professors from major universities (so far I only noticed universities in the USA).

It looks so good that I signed up for three courses. Now I have no excuses not to learn R.

The link to the homepage is: https://www.coursera.org/courses
