Run a gadget

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.
