Don't Take it From Us

Our learners say it best.

Very easy to understand and a great introduction to R! It even was fun! Really recommend it.

Irene Carrión Barberà Postdoctoral researcher · University of Washington

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.

Sue Reinert

Thank you for the step-by-step tutorial and helpful tips!

Maria Trinh Student at WU Vienna

Very well explained for beginners. Looking forward to deep dive into R now!

Adrian Passler

This course was very helpful and explained in full detail with great demonstration examples. I would for sure recommend this to a friend that is not familiar with the application to get started on coding with R-Studio.

Efemena

This course will be a great intro to get users started with R.

What a great introduction to R! I have worked in Stata and SAS, but have been wanting to learn R for sometime. David's videos are fantastic - a great pace for those familiar with other programs or those for whom R is the first - and the best part is you get to go back to them as many times as you need or want! I'm excided to dive into the other R for the Rest of Us courses!!

Courtney Dillingham Nurse Epidemiologist

Great instruction, I would recommend this course. Thanks.

Nina Liimatta UMKC

Your intro course makes me feel like R is not as daunting as I initially thought and it is something I can learn (with time).

An excellent clear outline of some of the key fundamental processes in R enabling you to import, clean, process, visualise and communicate your data. Great teaching!

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.

NOAA Fisheries West Coast Region R Training Website

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...
