“A great introduction to the fundamentals of R and RStudio.
“It’s like I’ve broken through a wall that had been stopping me [from learning 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.
“I learned very much from this course, and I now have a better understanding of how to use Git and GitHub with R. Before this course, I was unsure what GitHub was really about and how to integrate GitHub into my workflow. Now I feel more confident to make it an integral part of my work in R, and I am relieved to have a much better handle on version control. I have hope that it will be a great tool for collaboration going forward.
“What a great introduction to R! I have worked in Stata and SAS, but have been wanting to learn R for sometime. David's videos are fantastic - a great pace for those familiar with other programs or those for whom R is the first - and the best part is you get to go back to them as many times as you need or want! I'm excided to dive into the other R for the Rest of Us courses!!
“I just want to say how much I enjoyed R in 3 Months with R for the Rest of Us. It was a really great course. I was very intimidated to learn R. I finished my PhD and we were mostly working with SPSS and I started a new role where it became apparent that I needed to use and learn R pretty quickly. David and Charlie were great in helping me get up to speed and start working in R nearly every day. They make it quite fun and enjoyable to learn how to start exploring this great new, wonderful world of R. I got a lot of individualized attention and so it's a great course. I couldn't recommend it more.
“As we get to the end of the course, I'm feeling so much stronger in my ability to work with my data and make the visualizations I need. In the first part of the course I kept thinking, "I'm not sure if this is more time-efficient than using Stata"; later on I felt that it would be best to do my data wrangling in Stata and my data vis for maps and complex plots in R; and now I'm starting most of my new projects in R, as RMarkdown files, and planning forthcoming analyses with collaborators in 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!
“thanks - helped a lot to get started with R
“I am speechless! I have been trying to feel comfortable with R for so many years. I used to spend so much time looking for resources on the internet, trying to put all the pieces together, and I was always defeated. This course is an excellent shortcut to learning 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...
