“Solid intRo to R :)
“Excellent intro to R in about an hour! Thank you!
“As I had never used R before, this course helped me learn the basics of R and the different methodologies for data visualization and coming up with errors.
“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 is one of the best introduction to R courses that I have taken. It is simple yet very powerful. I have learnt a lot of things in one day which were very confusing to me for the past 2 years. Thank you for opening my eyes and allowing me to see the possibilites that are there in R. I highly recommend this course to anyone starting out in R.
“This course helped our office and myself grow. David is a great teacher and his videos are very easy to follow along and by letting us use our own data, we are able to see for ourselves where we need to grow and what to accomplish.
“What a fantastic introduction to R. David is a brilliant communicator.
“Absolutely, R for the Rest of Us was very helpful and informative. The content was clear, structured, and easy to follow. David did an amazing job breaking down complex topics into manageable, real-world examples. I'm walking away feeling much more confident using R in my public health work.
“Easy to understand and clear explanation of the R and RStudio
“I started learning R and GGPLOT by relying on books (e.g., R for Data Science) and youtube. This left me with a fragmented knowledge, since few of these sources approached teaching R and GGPLOT from a holistic manner. Getting Started with R patched up many of those holes, while giving me with invaluable tips as to how to secure future advise and support.

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...
