Chapter 15 Shiny

RStudio’s introductory tutorials for shiny provide an excellent introduction to this tool. Shiny is an R package that is for developing web applets using R. See RStudio’s shiny gallery for example shiny applets such as a Covid Tracker and RadaR an interactive open source software tool for Rapid Analysis of Diagnostic and Antimicrobial patterns in R.

The shiny package provides function to quickly build a UI and use R code to reactively change plots and analyses shown to the user as the user changes options provided by your UI.
