I have been diligently devoting a few minutes each day to learning R. I already know SQL relatively well and I know a little python. What is the best way to spend the few minutes I have each day?
First of all, dedicate more than 5 minutes. That’s hardly enough to open up R and look up one new function.
Read Intro to Statistical Learning in R (ISLR) and work through the exercises at the back of each chapter.
