Chapter 3 R Technicians
3.1 Updating dynamic content
3.1.1 Shiny App Content Updates
To render changes made to content in a Shiny app, navigate to the folder that contains the application files to run the app. Shiny apps are served from a standard folder where they are symbolically linked to source files. These folders contain the global.R, ui.R, server.R scripts that run the app.
- global.R: functions used in ui.R and server.R can be defined here, sourced here from other files or in loaded libraries
- ui.R: defines the user interface, or display, of the contents in the shiny app; this is navigable through the bookmarks in the lower left menu of the Code panel in RStudio
- server.R: back-end server functions to populate the user interface; this is also navigable through the bookmarks in the lower left menu of the Code panel in RStudio
