A lot of programmers dislike R for the same reason they dislike PHP: weak typing.

If you can get over that, though, there's a lot to like about R. It's sort of like a hybrid between a Lisp and an array language.

Javascript and C also have weak typing. And Python isn't statically typed, it's just that like Ruby, it doesn't allow implicit conversion, except with numbers.

Weak typing? No, it's not. R is a strongly typed language.

Iirc the scoping is also very strange. Certainly not as bad as mathematica, but bad nonetheless.
