I have started really enjoying R (with tidyverse) because it allows me to present complicated topics in a very simple manner. I can easily embed short R snippets and LaTeX equations in an Emacs Org mode document, and then export it as a very nice-looking easy-to-read HTML or PDF document with basically no effort other than coming up with the text itself.
I'm working on my data science degree, and this is my method as well, though I'll admit I don't know much R yet so I'm using it very simply. I'll usually have a mix of python, R, octave, etc snippets.
It is incredibly liberating.
