“Very good explanations in an entertaining way, I really enjoyed the course
“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!
“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.
“Excellent course to know the basics of this great tool (R).
“Started today with the "Getting started with R" course and although being already a not-so-bad R user clarity and some helpful tricks proved really great. Looking forward to attend the other courses. Thank you!
“I'm extremely proud and happy to announce that in March I received a scholarship for R 3 in Months Course by R for the Rest of Us thanks to David Keyes and Charlie Joey Hadley. I want to express my deep appreciation for this amazing program, which is greatly helping me in significant professional growth. Their expertise, dedication, and commitment to helping students succeed in their different fields using data analysis and visualization in R is admirable and praiseworthy. Doing this course was definitely an enjoyable experience. Eternal thanks to R for the Rest of Us and to David & Charlie.
“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!
“This was an easy to follow course.
“This is an excellent introduction to R and Rstudio and the capabilities of R. It was easy to understand and the exercises and tips were very helpful. I learned a lot. Thank you for offering this us to dip our toes into using R.
“I've been dipping my toes in the R water for many years, your site and approach has been the most accessible and useful by far!

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...

Taking a Typst template and...
