Our learners say it best.
“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.
“Thank you for the step-by-step tutorial and helpful tips!
“Thank you for the nice course. It was really helpful to learn the basics.
“Thank you David for all you do. I am a newbie to data tools, and I've been wearied of them. Though my pace was a bit slow, I did understand and appreciate your style of coaching. I am now able to venture and learn more!.
“Very good explanations of the basics of R, practical exercises are always welcome
“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.
“Quick, user friendly introduction into R programing. Very well put together and presented.
“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!
“This course really helped me demystify the process of getting started in R!! I was so so scared and waited until the last necessary moment to get started and this guided me to get to a place where I can be successful and confident. Highly recommend!
“This course was a straightforward and quick way to learn the basics about using 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...
