Our learners say it best.
“Its very useful course for beginner! Thank you so much :)
“If an 84-year-old complete coding novice can get something out of this course, anyone can. The ability to ask questions and get answers was especially helpful.
“This course was a straightforward and quick way to learn the basics about using R.
“It’s like I’ve broken through a wall that had been stopping me [from learning R]!
“I was overwhelmed with the prospect of starting to use R, especially given all the many websites and resources available online. This course was exactly what I needed - clear and organized ideas, step-by-step instructions, and the use of real examples and practice strategies. Such a wonderful resource!
“Really good introductory course. Even with the basic knowledge of R that I have, the course went through some aspects and details that were very useful.
“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.
“This course helped our office and myself grow. David is a great teacher and his videos are very easy to follow along and by letting us use our own data, we are able to see for ourselves where we need to grow and what to accomplish.
“I have been working with R for the past 3 years and consider myself to be a proficient user, however going through R in the 3 Months course made me realize the breadth of possibilities R offers and how much more there is to learn. I was able to pick up so many handy tricks that made my R workflow much more efficient and easier to reproduce.
“Learning R and GGPLOT with books (e.g., R for Data Science), and youtube provided me basic knowledge with many potholes. Getting Started with R assisted me in reorganizing my foundations, making sense of the patchwork of knowledge I have, while addressing several of my gaps. Of particular value are the tips as to how securing help for learning about the nuances of tidyverse functions.

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...
