“This course is a short, clear, and comforting way to get started with R starting with installing the package and opening a dataset to viewing data and defining missings and variable types. I highly recommend it if you plan to start using R.
“Started today with the "Getting started with R" course and although being already a not-so-bad R user clarity and some helpful tricks proved really great. Looking forward to attend the other courses. Thank you!
“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?
“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.
“I had dabbled in R a number of years ago and needed to get a refresher of the basics before getting back into coding and data analysis using R. Getting Started With R was excellent as a refresher and would be just as good for those starting out. The videos are easy to follow and they provide practical examples to follow along. I would recommend to anyone looking to understand R
“This course will be a great intro to get users started with R.
“This course is a gem. It rests on a solid perspective as to how to bring R and allied resources in a comprehensive toolbox. It allows one to understand how to use R from building a data frame to creating meaningful graphics and reports. I can’t help but to marvel at Dr. David Keyes’ ability to bring together different r packages and making them accessible to the rest of us.
“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.
“Yes, this course is so easy to understand!

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...
