Our learners say it best.
“I have been working with R for the past 3 years and consider myself to be a proficient user, however going through R in the 3 Months course made me realize the breadth of possibilities R offers and how much more there is to learn. I was able to pick up so many handy tricks that made my R workflow much more efficient and easier to reproduce.
“An excellent clear outline of some of the key fundamental processes in R enabling you to import, clean, process, visualise and communicate your data. Great teaching!
“I have learned a lot from this introductory course in R. I would recommend for any one trying to learn R to start with this course. Thanks, R for the rest of us.
“I am a complete beginner and managed to follow the tutorial successfully. I will keep learning.
“This was an excellent use of time to get started in R. It takes less than an afternoon and I made a lot of progress in using R that I hadn't been able to do before. It was very clear - key words were defined - I didn't feel like I was struggling with jargon - highly recommend for those starting from zero with R.
“Really good introductory course. Even with the basic knowledge of R that I have, the course went through some aspects and details that were very useful.
“Really helpful and clear!
“WOW! Thanks, this was challenging. I am learning something new that I hopefully will retain.
“Very well explained for beginners. Looking forward to deep dive into R now!
“Awesome course! It helped me understand the nitty-gritty parts of coding with R that I had struggled with so far. David is an awesome instructor who explains everything in an easily understandable manner. And if you still struggle, there's always the repeat button. :)

How to Get Started Using AI with R
May 27, 2026
There are so many ways to use AI with R now that it's genuinely hard to know where to start. Should you just use ChatGPT in a browser tab? Install something into your code editor? And if so, which one? I made a video walking through the main options, with the pros and cons of each. The simplest approach is the one most people start with. Pop open ChatGPT in a browser and ask it R questions the same way you'd ask anything else. It works, but you end up bouncing back and forth between the...
Introducing the {pdfcheck} R package for checking the accessibility of PDFs
February 5, 2026
Are the PDFs you're creating accessible? Can someone using a screen reader navigate them? Is the color contrast sufficient for people who are colorblind? These are questions we've been getting a lot from our consulting clients at Clarity Data Studio. And honestly? When we reviewed our own PDFs, we found there wasn't a really great tool to check accessibility and give us actionable steps to improve. So we decided to build our own. It's called {pdfcheck}, and it's an R package that helps you...
