## Book
[![](https://r4pde.netlify.app/cover.png){style="float: left; margin-right: 30px; border: 2px solid steelblue" width="200"}](https://r4pde.netlify.app/)**R for Plant Disease Epidemiology** ([R4PDE](https://r4pde.netlify.app/)) is a dynamic online book rooted on the teaching notes of my graduate course, FIP 602 - Plant Disease Epidemiology, which is offered every year for students in the [Graduate Program in Plant Pathology](http://www.dfp.ufv.br/grad/) of the Universidade Federal de Viçosa.
This book is for those interested in studying and modelling plant disease epidemics using R. It provides context and showcases various methods for describing, visualizing and analyzing epidemic data collected over time and/or space. Users should have have a foundational knowledge of R to run the examples.
## Apps
I have developed, myself or in collaboration with students, web applications to support research and teaching. These are made with R + Shiny.
