Our learners say it best.
“I have tried multiple times to get started with R and failed, this is the first time I'm beginning to appreciate the logic of it!
“Getting started with R is an excellent source for those looking to do just that. The instruction is gentle, and hand-holdy, providing clear instruction of what the code is actually doing. I've used this course to help team members who have been longtime SAS users get their feet wet with R and the feedback has been nothing but positive. I would easily recommend this course to anyone who wants to learn R but gets overwhelmed with online sources that either spend too much time on the mechanics of R, or move too fast through topics. This course strikes a perfect balance of skipping all the stuff under the hood, while also taking the time to explain what to do to get your hands on your data and how to do it. A+
“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!
“One of the most informative courses I have ever taken. The weekly videos are extremely helpful and show step by step how to code in R. In addition, you will have access to these videos even after the course finishes. I was very confused on how to use R just by reading books, but after this course I feel a lot more confident in R.
“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.
“For me as a university student who wants to learn everything new, I was attracted to your course when my doctor talked about it. So I will continue learning it until the end. Your explanation was comprehensive, useful and simple. In addition, please wished me success because I will use this programming language during my studies for my university research.
“I just created my very first bar chart in R, and I could not have done it without Fundamentals of R course over at R for the Rest Us.
“Solid intRo to R :)
“Definitivo, es un muy buen inicio. He manejado r antes y aprendí muchas cosas nuevas. Gracias David y equipo por un muy buen trabajo. Abrazo, Martha Lucía.
“This was a great course for me, just starting to use R and now I got just the introduction I needed to be up and running using R.

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...
