shiny (version 1.10.0)

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
)

Value

The value returned by the gadget.

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.

Examples

if (FALSE) {
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))
}
