Скачать или смотреть Python vs R: some performance comparisons | R Programming

Calling Python from R is easy and is useful to access Python libraries. In this RStats tutorial, we show you how to set up a Python session within R and some tips for translating your code. We will also run similar algorithms in Python and R to see how they compare for speed! Subscribe to learn more about R and how you can make your code faster. 🐍
