The Epidemiologist R Handbook

The free R manual for applied epidemiology and public health


What is the Epi R Handbook?

The Epidemiologist R Handbook, from Applied Epi, is a free digital reference book for R code, that is specifically designed for people working in applied epidemiology, public health practice, and disease control.

The “Epi R Handbook” is available at, and for offline use via our download page.

Who wrote it?

The Epi R Handbook was written by an independent, grassroots collective of 50 epidemiologists based around the world, who eventually formed Applied Epi. They worked in their spare time (during the COVID-19 pandemic response!) to create this free resource for the community. The Handbook was launched to the public on 10 May 2021.

As of June 2024, the Epi R Handbook had been used over 3 million times, by 875,000 unique people, in 203 countries. About half of the users were based in low- and middle-income countries (LMICs).

The Epi R Handbook has been incorporated into training curricula of numerous institutes and agencies, including Doctors without Borders (MSF), the World Health organization, national Field Epidemiology Training Programs (FETPs), and universities.
