\title{Run a gadget}
\usage{
runGadget(app, server = NULL, port = getOption("shiny.port"),
viewer = paneViewer(), stopOnCancel = TRUE)
}
\arguments{
\item{app}{Either a Shiny app object as created by
\code{\link[=shiny]{shinyApp}} et al, or, a UI object.}
\item{server}{Ignored if \code{app} is a Shiny app object; otherwise, passed
along to \code{shinyApp} (i.e. \code{shinyApp(ui = app, server = server)}).}
\item{port}{See \code{\link[=shiny]{runApp}}.}
\item{viewer}{Specify where the gadget should be displayed--viewer pane,
dialog window, or external browser--by passing in a call to one of the
\code{\link{viewer}} functions.}
\item{stopOnCancel}{If \code{TRUE} (the default), then an \code{observeEvent}
is automatically created that handles \code{input$cancel} by calling
\code{stopApp()} with an error. Pass \code{FALSE} if you want to handle
\code{input$cancel} yourself.}
}
\value{
The value returned by the gadget.
}
\description{
Similar to \code{runApp}, but handles \code{input$cancel} automatically, and
if running in RStudio, defaults to viewing the app in the Viewer pane.
}
\examples{
\dontrun{
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))
}
