“Easy to understand and clear explanation of the R and RStudio
“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!
“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.
“I think one of the biggest benefits of R in 3 Months is having continued access to all of the resources. Thanks so much for making that available to us!
“Hello, i really appreaciated the way the actions in R were described. However, i still struggle to understand the concrete benefit of R. I am wondering, wheter R can do controlling reports as well ? I mean, i work for a retail company, and every month i have to prepare revenue, profit reports of sales of the different product groups. I usually prepare these reports in Excel..... so i monthly have to export all the necassary data from our ERP-System into Excel sheets and then i have to collect and prepare them in one report. Do u think R Studio can do the same thing so that it is less effort for me?
“It was a great quick start into how to use R. Thank you so much!
“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.
“Very good explanations in an entertaining way, I really enjoyed the course
“This was a great course for me, just starting to use R and now I got just the introduction I needed to be up and running using R.
“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.

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

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...
