Don’t just randomly accuse people of making bad faith arguments. I’ve use R a lot and while it has its issues, it has a much better interface than numpy.
R provides an interface to dataframes and matrices, whereas numpy is just for matrices (and their generalisations, arrrays). I think the appropriate comparison is between base R and Numpy + pandas. (FWIW, I agree with your major point, but then I learned R first so that may be biasing me).
It’s hardly random. R functions could be noun-adjective or adjective-noun or underscored or camelCase or dotted ... and that’s just naming conventions. If someone, like you, says that Numpy sucks, but R is the real masterpiece, then that’s totally insincere. The good thing about R is that it’s free, the C FFI is OK and R-studio is decent. It’s API is a patchwork. It’s cool to say Java sucks or Python sucks on the orange site because they’re popular and if you say something popular sucks, well you must be a pretty cool guy who is smarter than all those rubes out there. The arguments are almost always total nonsense, though.
