I'm a Python programmer who's interested in learning a bit of R. I'm still considering what exactly to pick up as a secondary language with R and Rust as my current considerations.
What I basically want to ask is what exactly is R good for? I've heard alot of things about Data Science in R. But I think Python is also used alot in Data Science. So is there any advantage of R over Python?
Assuming I go ahead with R, I'm curious as to what are the R equivalents to libraries like PyQt5 for GUI development. Something modern and new I mean. Something like JavaFX is also good. I've had experience with both.
