Creating web applications with Shiny (2/2)

Learn how to make interactive tables, graphs and text from data.

In a two-sessions workshop, Nick van Doormaal will demonstrate how to use the shiny package to create interactive web applications. Note that this is the second session of a two-sesssion workshop. The first session (on Thursday March 17) was be a basic introduction on the different components of a shiny app. In this second session we explore into more depth how ‘reactivity’ works, an important component of most shiny apps.

To prepare for the workshop, you may want to take a look this key resource for shiny, in particular Chapter 3.

In advance of the workshop, we suggest you install these two R packages (just copy and paste this line into your R Studio Editor and run it)

install.packages(c(“tidyverse”, “shiny”))

Nick van Doormaal is a former PhD candidate at the NSCR and currently a data analyst at the environmental service of the province of Gelderland. He got into R during his MSc thesis and internship and has been using R ever since.
