R, OPR, etc

[Skyehawk]

Hello to the rather specific part of the FIRST community I am targeting,
I was reading over OPR calculation and other such calculations in order to calculate offensive contributions and some ideas started to weasel its way into my head, therefore I must pursue them. I should pick up the R language relatively easily, as it seems to share many common elements with Python and Matlab. I was wondering are there some resources that you guys could point me towards to aid with my learning? I am slowly falling deeper end deeper into the statistical analysis rabbit hole and any help to ease the future confusion I may have is greatly appreciated.

Happy New Year!
