Yep I used R. I’m just figuring out how to do it myself. R has some decent online help, and if you go to the Sportsvision site you can download the presentations from last year’s Pitch F/X Summit where Dave Allen talked about it. Once I get a little more comfortable I can write something up and post it here.
For this particular one I binned the data by 4″ by 4″ squares and just did the SLGCON values within those squares.
