Don't Take it From Us
Our learners say it best.
“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 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.
“R has enabled me to explore my data more deeply and take control of my data visualizations. I would highly recommend the R in 3 Months program to anyone who wants to learn R.
“What made me decide to engage with R in 3 Months was the focus on accessibility and inclusivity. It promised to simplify the complexity of R and make it approachable for someone like me who didn't have a strong background in programming or statistics. Before the course, my use of R was quite limited and mostly experimental, and I was not fully comfortable with the language. However, after completing R in 3 Months, my confidence and competence in using R have significantly increased. Now I use R regularly for a variety of tasks, such as data manipulation, data wrangling, data cleaning, statistical analytics, and data visualization. This has allowed me to leverage R more effectively in my professional projects.
“I am just starting R and this course was really helpful ! Thanks a lot :)
“Hi! This course is just the simplest way I have found to understand R. Thanks a lot!
“It took a while but finally completed all the modules - really helpful when I needed it and glad I can always go back :)
“Very nice explanations and easy to follow. ThankYou!
“A serious course for a beginner. Watch it with pen and paper and write down important things.
“Before the course, I could kind of read R code, and I could put patches together and I would Google stuff, copy and paste and hope it worked. Sometimes it did, sometimes it didn't. Now after the course, I'm much more R literate and much more confident.

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...
