Testimonials
Don't Take it From Us
Our learners say it best.
“Very easy to follow along and learn a lot in a short amount of time!
“At first, I thought R was only for stats-minded people and was outside of my wheelhouse as a person who deals more with data extraction, transformation and reporting. However, after going through the R for the Rest of Us courses and learning from David about the vast capabilities of R, I quickly discovered R IS EXACTLY for people like me! Its strength in creating efficient data processing and reporting workflows is beyond amazing, and David – with his deep knowledge and genuine desire to teach and build capacity – is the perfect R guide!
“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!
“As I had never used R before, this course helped me learn the basics of R and the different methodologies for data visualization and coming up with errors.
“The knowledge I gained over the course of doing the assignments for R in 3 Months and the final assignment is something that I use every day. I've also been able to find more opportunities and ways to use R to solve problems that I've had for years, as well as having discussions about upcoming projects and finding ways that I can use R in them in a way that I would have never sort of thought before.
“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.
“Your intro course makes me feel like R is not as daunting as I initially thought and it is something I can learn (with time).
“All the basics to using and learning R, I'll definitely continue with the next course.
“Really helpful and clear!
“As someone who has never coded before, this course was a lifesaver. Dr. Keyes takes you on an incredible journey as he follows a step-by-step approach to familiarise you with R and making it less intimidating to code. This course has encouraged me to continue learning R and hopefully, become proficient in it in the coming future.

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...
