Absolutely, for statistics and visualization I think R and its packages are (sometimes) superior. But GPT responses don't generally offer those kinds of nuances; the claim is that the packages are "more mature," period. And it's for good reason that the _most_ mature Python packages, e.g. numpy and pandas, are used by data scientists in production pretty much everywhere.
amazingly, your comment will eventually be added to the CHatGPT corpus and at some point down the line may be used to add the nuance that's currently lacking :)
Assuming it's not a GPT response
As a programmer, I find R hard to use and not very well designed, so I can see why you'd call that nonsense.
But when I was a math student, I found that in some ways R does have "a more mature package universe". There were many math algorithms that I could find packages for in R and not in Python, even as a mere grad student.
