Don't Take it From Us
Our learners say it best.
“I've used R quite a bit in the past, but until taking this course, I felt like I was navigating a maze with my eyes closed -- running bits and pieces of code and troubleshooting each time I bumped into a wall, but never truly understanding where I'd been or where I was headed. "Getting Started with R" is the map to the maze that I never knew I needed, but now don't know how I'd live without! David clearly explains foundational concepts and makes R so much easier to understand. Whether you're brand-new to R or have been using it for years, I highly recommend this course.
“Very nice explanations and easy to follow. ThankYou!
“For anyone wanting to learn R, I cannot recommend this course enough!
“I thought learning R would be difficult but the introduction was great and has given me hope that I can be good at R. Really loved how the videos were informative and easy to follow along. Thank you.
“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
“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.
“I just want to say how much I enjoyed R in 3 Months with R for the Rest of Us. It was a really great course. I was very intimidated to learn R. I finished my PhD and we were mostly working with SPSS and I started a new role where it became apparent that I needed to use and learn R pretty quickly. David and Charlie were great in helping me get up to speed and start working in R nearly every day. They make it quite fun and enjoyable to learn how to start exploring this great new, wonderful world of R. I got a lot of individualized attention and so it's a great course. I couldn't recommend it more.
“Really helpful and clear!
“Absolutely, R for the Rest of Us was very helpful and informative. The content was clear, structured, and easy to follow. David did an amazing job breaking down complex topics into manageable, real-world examples. I'm walking away feeling much more confident using R in my public health work.
“My team is continuing to use the R we learned from you and your team - it's been a game changer for us and we've only scratched the surface on what we know how to do.

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...
[Livestream Recording] How to Make High-Quality PDFs with Quarto and Typst
November 20, 2025
Last week, we released our massive blog post on making report templates using Quarto and Typst. R for the Rest of Us consultant Joseph Barbier and I did a livestream yesterday where we went over several questions submitted to us on this topic. 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...
