We host Applied Epi Community - a Q&A forum for R code and public health practice.

We offer a global R Help Desk for timely troubleshooting and assistance.



Free. Efficient. Cutting-edge.
For a Haitian epidemiologist, using our free Epi R Handbook to transition routine analyses to R meant more flexibility, confidence, and time for systemic change.

With R I can do anything. What took 10 hours in Excel, I do in less than 1 hour. Also it is easier to detect if there is a mistake.

Not just a new tool, but a new culture.
In open-source software like R, users have the agency to be creators - to share localized solutions. Innovation is decentralised and career pathways are opened.

For Applied Epi, R is just the beginning.
Adoption of R as the free common analytical language will facilitate higher-quality analyses, interoperability between agencies, reproducibility, overdue investment in ground-level personnel, and standardisation of scientific methods and training.
