> Heck, R isn't really that accessible to most programmers either.

R is objectively a bad programming language. However, it is by no means inaccessible. I have no statistics background whatsoever, and I managed to learn enough R to be dangerous in a mere week. Other than the 1-based indexing and the utterly disgusting dynamic dispatch mechanism (you could simply not to use the latter), R is surprisingly pleasant to use. What I enjoyed the most is that vectors and matrices are first-class values, not objects that are referred to through pointers. It's probably copy-on-write under the hood, but I don't need to care. Hallelujah!
