“What a great introduction to R! I have worked in Stata and SAS, but have been wanting to learn R for sometime. David's videos are fantastic - a great pace for those familiar with other programs or those for whom R is the first - and the best part is you get to go back to them as many times as you need or want! I'm excided to dive into the other R for the Rest of Us courses!!

“R in 3 Months is a wonderful resource for beginners or experienced R users alike – truly the best R resource I know for learning and expanding R skills.
“A great introduction to the fundamentals of R and RStudio.
“David, Just a note to say thank you for a clear, concise and straightforward approach to R. Shout out to Chris Garmon, University of Missouri-Kansas City, MO professor in graduate school course, Research Methods in Public Administration for steering students to your free, easily understandable course. You do a great job taking the scariness out of R by taking us step by step through learning how to use R and explaining the power R has in being able to tell a story through data and analyzing information to make decisions. Professor Garmon told us that The Washington Post uses R for it's data and that's quite a seal of approval. Thanks again for a great course. Bernita Cauthon, Kansas City, Missouri

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...
