Our learners say it best.
“A great introduction to the fundamentals of R and RStudio.
“I think one of the biggest benefits of R in 3 Months is having continued access to all of the resources. Thanks so much for making that available to us!
“I learned very much from this course, and I now have a better understanding of how to use Git and GitHub with R. Before this course, I was unsure what GitHub was really about and how to integrate GitHub into my workflow. Now I feel more confident to make it an integral part of my work in R, and I am relieved to have a much better handle on version control. I have hope that it will be a great tool for collaboration going forward.
“What a fantastic introduction to R. David is a brilliant communicator.
“I am just starting R and this course was really helpful ! Thanks a lot :)
“The course is highly accessible in its pedagogical style, its language, and practicality. I've never coded before and this course allowed me to feel confident about my R journey! My favorite part was that David was reachable to help with queries!
“Very nice explanations and easy to follow. ThankYou!
“This course was very helpful and explained in full detail with great demonstration examples. I would for sure recommend this to a friend that is not familiar with the application to get started on coding with R-Studio.
“Really helpful and clear!
“Fantastic and lovely

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...
