That's simply not true. R doesn't store old versions, which is actually brilliant because your code breaks when your dependencies rot. Python will silently upgrade numpy as a transitive dependency and break everything, which is much worse. MRAN also has daily snapshots which is normally how i handle stuff that will never be updated. I also specified building an R package which does handle dependencies versus the python equivalent which does not. I'm not saying R is good, I'm just saying Python is way worse.
