It's clear there are a lot of strong opinions about R!

One kind of obscure problem I run in to is R's embrace of a global namespace. Package developers sometimes assume people are using this namespace, and access it via the globalEnv() function. This means that to use the package anywhere else, you basically have to patch their code.

(in contrast, I don't even think about problems like this occurring in python packages. Worst case scenario, can just use a subprocess )
