Don't Take it From Us
Our learners say it best.
“I loved it. I absolutely loved it. The notepad can be very disheartening. You know immediately that there will be a lot of coding involved, but once you start the journey, you just want to go on. By the time I got to the Objects and Functions phase, I was saying goodbye to Excel. I also loved the quote about the coder. I confirmed this with my coder friends and they agreed with it 100%. I can now feel confident getting into R and coding without fear. This has been mind-opening. I would definitely recommend this course!
“Quick, user friendly introduction into R programing. Very well put together and presented.
“Thanks for effectively introducing me to R. It's a very helpful course.
“I have learned a lot from this introductory course in R. I would recommend for any one trying to learn R to start with this course. Thanks, R for the rest of us.
“I’m wrapping up the R in 3 Months course through R for the Rest of Us now, and it’s been the best professional development experience of my life, hands down.
“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.
“Great, easy to follow, clear into to R. I've taken a couple of other "R intro" trainings and was starting to feel discouraged about being able to use R. This training restored my confidence :)
“Thank you David for all you do. I am a newbie to data tools, and I've been wearied of them. Though my pace was a bit slow, I did understand and appreciate your style of coaching. I am now able to venture and learn more!.
“This introductory course provided me with an excellent foundation in the R programming language. I had previously started learning about this powerful tool, but life circumstances interrupted that journey. Thanks to this course, I was able to resume my learning process, and I look forward to continuing it for much longer. Thank you!
“Fundamentals of R was an approachable, helpful course. I recommend it for anyone who's new or new-ish to R. The format is extremely helpful and the course's user interface makes things really easy.

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...
