Our learners say it best.
“Thank you David for all you do. I am a newbie to data tools, and I've been wearied of them. Though my pace was a bit slow, I did understand and appreciate your style of coaching. I am now able to venture and learn more!.
“This was a great introductory course!
“This is approachable and accessible. I'd recommend this program to a friend as a great way to learn enough about R to take away the fear of the difficulty of learning anything relating to code.
“A great intro with simple explanations to get someone starting out in R engaged on the topic.
“thanks - helped a lot to get started with R
“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!
“It was really great and helpful, thank you very much!
“The knowledge I gained over the course of doing the assignments for R in 3 Months and the final assignment is something that I use every day. I've also been able to find more opportunities and ways to use R to solve problems that I've had for years, as well as having discussions about upcoming projects and finding ways that I can use R in them in a way that I would have never sort of thought before.
“I am just starting R and this course was really helpful ! Thanks a lot :)
“I consider myself lucky as I found Mr. David's courses in R. I loved every single tutorial in this course. What I love most about this course is that it teaches you bit by bit and step by step, literally from zero to hero. I'll recommend these tutorials to anyone interested in R programming. I'll take the next course, "Going Deeper with R." I have no intention of stopping until I finish every tutorial on this website. Thank you so much, Mr. David. I owe you a lot. Greetings from Egypt.

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...
