R and Python statistics

R and python are the leading languages for data science. I have written some tutorials. I intend to write more as I am taking a course on R.

Update

Updated: Tutorial 1

If you are interested in Python and Kivy, I intend to have tutorials at pythonmobile. 

If you don't know Python, you may check my pythonaudio site, since I talk about the important elements in the beginning such as lists, tuples and dictionaries.

However, soon I intend to also start focusing on JMonkeyEngine 3, for 3D game programming in Java.
