> Yes, Python makes preprocessing easy, but that doesn’t mean you can’t use R if you need to clean up your data. You can use any language. In fact, in many cases, it’s structurally unsound to mix up your data purification routines with your analysis routines. It’s better to separate them. And if you’re going to separate them, why not use any language you like? That may indeed be Python, but it could be Java, C, or even assembly code. Or maybe even you want to preprocess your data within the database or some other storage layer. R doesn’t care.

The hell does this even mean?
