But there are more options to learn R. I’ll start with a free one:

  • Codecademy: Codecademy offers beginner-friendly R courses including the free courses, ‘Learn R’ and ‘Learn Statistics with R’, and the premium (‘Pro’) courses, ‘Analyze Data with R’ and ‘Learn Linear Regression with R’. For more on Codecademy Pro, see my Codecademy Pro review.

  • Coursera: If you’re looking to invest and accelerate your future data science career, Coursera partnered with John Hopkins University to offer an amazing R Programming Specialization that covers all of the skills you need not just in the language but in the job.

  • Other Free Learning Resources: If you’re thinking, “More free stuff, please,” I can deliver on that too: I’ve compiled over 70 free coding resources. Being a beginner is great, because the beginner phase of learning programming is inexpensive. Take advantage of these free resources while you get your footing in programming.

I hope this was helpful. Thank you so much for reading, and I’ll see you in the next article. 👋😁
