Our learners say it best.
“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.
“Very easy to follow along and learn a lot in a short amount of time!
“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.
“A great introduction to the fundamentals of R and RStudio.
“LOVED the course! Thank you so much for keeping everything high level enough that we don't get lost in the weeds but also providing so much helpful information. I've gone through other courses for beginners and came away still not knowing what a package was or how to import data. This course was perfect.
“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.
“Your succinct lessons were the gateway for my fast advancement. By learning the basics from this course, I have already gone down the deep end of conducting inferential statistics, machine learning, and other advanced analyses. I've already impressed my boss with my first HTML report to our VP!
“great intro to R. I enjoyed it
“Very good explanations about how to using r, also he doesn't go fast so you can understand way better everything. Highly reccomendated :)
“It was really great and helpful, thank you very much!

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...

Taking a Typst template and...
