I deeply loath R for its terrible type idiosyncracies, syntax, and slowness.

However, even I must admit that it is incredibly good at what it was meant to do - analyse and display data. (And yes, the tidyverse is a huge improvement of the syntax, although it's telling that they basically reinvented the language to do so.)

As an ecological modeller, I create my actual simulation models in Julia, because it is a much, much better language for any real programming. But I still analyse the output in R.
