Don't Take it From Us
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.
“Definitivo, es un muy buen inicio. He manejado r antes y aprendí muchas cosas nuevas. Gracias David y equipo por un muy buen trabajo. Abrazo, Martha Lucía.
“I'm extremely proud and happy to announce that in March I received a scholarship for R 3 in Months Course by R for the Rest of Us thanks to David Keyes and Charlie Joey Hadley. I want to express my deep appreciation for this amazing program, which is greatly helping me in significant professional growth. Their expertise, dedication, and commitment to helping students succeed in their different fields using data analysis and visualization in R is admirable and praiseworthy. Doing this course was definitely an enjoyable experience. Eternal thanks to R for the Rest of Us and to David & Charlie.
“Fantastic and lovely
“For me as a university student who wants to learn everything new, I was attracted to your course when my doctor talked about it. So I will continue learning it until the end. Your explanation was comprehensive, useful and simple. In addition, please wished me success because I will use this programming language during my studies for my university research.
“Gone are the days of copy-pasting SPSS output to Excel, and Excel charts to Word, over and over again! Learning R was one of the best professional investments I have ever made, and has been invaluable in streamlining my work UBC Faculty of Medicine and the Justice Institute of British Columbia.
“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.
“Really helpful and clear!
“I shared R for the Rest of Us with my daughter who is in college and trying to learn R, and she texted me an hour later..."OMG, this is 1000x better and easier to understand than the other videos I saw." Thank you David for making R so easy to understand!
“This corse is very effective because of the clean and proper communication and the better understading and this course is very useful in our training of r programming lanugage

Childhood Bereavement Estimation Model Reports
Judi’s House/JAG Institute, a nonprofit in Colorado, provides support regarding childhood bereavement. In 2018, they created the Childhood Bereavement Estimation Model® (CBEM) to estimate rates of children losing a parent or sibling before adulthood. Annual CBEM reports were produced, but racial and ethnic data breakdowns were lacking until 2021. Partnering with R for the Rest of Us, they generated high-quality, easy-to-understand reports on bereavement disparities by race and ethnicity. These national and state-level reports, created using parameterized reporting and RMarkdown, help advance their vision that no child should be alone in grief.
Immunization Agenda 2030 Reports
The World Health Organization's Immunization Agenda 2030 (IA2030) aims to improve global vaccine access. To better report progress, the International Vaccine Access Center at Johns Hopkins University partnered with R for the Rest of Us in 2023. They produced 72 user-friendly country-level reports in English and French, using parameterized reporting. These reports highlight individual country progress, use less technical language than previous online scorecards, and are in a printable PDF format for review.
Improving R Training for NOAA Fisheries West Coast Region
NOAA Fisheries West Coast region (NOAA WCR) aims to maintain healthy fish populations along the west coast, with offices in California, Oregon, and Washington. Recently, they have increased their use of R, arranging internal trainings and seeking additional support in 2024 from R for the Rest of Us. They created a 6-week training program focusing on R fundamentals, advanced R topics, and GitHub integration. By the end, NOAA WCR staff efficiently produced technical memoranda and improved their workflows using R and Quarto.

How to make heatmaps in ggplot
May 1, 2025
Heatmaps are a common way of representing data. In this blog post, I'll show you how to make your own heatmaps using ggplot. In the process, you'll learn a bit about working with the {sf} package, specifically the st_make_grid() function to make a grid, the st_intersection() function to clip the boundaries of your geography to the grid you create, and st_join() to do spatial joins. This blog post is adapted from a lesson in the Mapping with R course . If you want to learn to make heatmaps...
Use shadows in ggplot to highlight findings
April 24, 2025
In our consulting work, we make a lot of the data visualization for parameterized reporting . It’s something I spoke about in my 2024 Cascadia R Conf talk, How to Make a Thousand Plots Look Good: Data Viz Tips for Parameterized Reporting . One example I gave in this talk came from our work with the Johns Hopkins International Vaccine Access Center and the World Health Organization . In this project, we made reports for the Immunization Agenda 2030 project, which tracks the progress countries...
