Our learners say it best.
“Good quick overview. I'm likely to take more courses from them in the near future. The mapping course looks very interesting.
“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!
“super cool!
“thanks - helped a lot to get started with R
“Before the course, I could kind of read R code, and I could put patches together and I would Google stuff, copy and paste and hope it worked. Sometimes it did, sometimes it didn't. Now after the course, I'm much more R literate and much more confident.
“Your spring class was amazing!! Well worth taking. Highly recommend.
“Really helpful and clear!
“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.
“I found this short course engaging, informative and interesting. I believe it has given me a good first clue of how to get started with R.
“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.

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...

In the livestream we covered several topics, including: Making complex elements that we used in the state-level immunization reports we recently created for the Johns Hopkins University International Vaccine Access Center. Taking a Typst template and...
