runGadget

Run a gadget

Description

Similar to runApp, but handles input$cancel automatically, and if running in RStudio, defaults to viewing the app in the Viewer pane.

Usage

runGadget(
  app,
  server = NULL,
  port = getOption("shiny.port"),
  viewer = paneViewer(),
  stopOnCancel = TRUE
)

Arguments

`app`	Either a Shiny app object as created by `shinyApp()` et al, or, a UI object.
`server`	Ignored if `app` is a Shiny app object; otherwise, passed along to `shinyApp` (i.e. `shinyApp(ui = app, server = server)`).
`port`	See `runApp()`.
`viewer`	Specify where the gadget should be displayed–viewer pane, dialog window, or external browser–by passing in a call to one of the `viewer()` functions.
`stopOnCancel`	If `TRUE` (the default), then an `observeEvent` is automatically created that handles `input$cancel` by calling `stopApp()` with an error. Pass `FALSE` if you want to handle `input$cancel` yourself.

Value

The value returned by the gadget.

Examples

## Not run: 
library(shiny)

ui <- fillPage(...)

server <- function(input, output, session) {
  ...
}

# Either pass ui/server as separate arguments...
runGadget(ui, server)

# ...or as a single app object
runGadget(shinyApp(ui, server))

## End(Not run)
