runApp

From shiny v0.12.2 by Winston Chang

Run Shiny Application

Runs a Shiny application. This function normally does not return; interrupt R to stop the application (usually by pressing Ctrl+C or Esc).

Usage

runApp(appDir = getwd(), port = getOption("shiny.port"),
  launch.browser = getOption("shiny.launch.browser", interactive()),
  host = getOption("shiny.host", "127.0.0.1"), workerId = "",
  quiet = FALSE, display.mode = c("auto", "normal", "showcase"))

Arguments

appDir: The directory of the application. Should contain server.R, plus, either ui.R or a www directory that contains the file index.html. Alternately, instead of server.R and ui.R, the
port: The TCP port that the application should listen on. If the port is not specified, and the shiny.port option is set (with options(shiny.port = XX)), then that port will be used. Otherwise, use a random port.
launch.browser: If true, the system's default web browser will be launched automatically after the app is started. Defaults to true in interactive sessions only. This value of this parameter can also be a function to call with the application's URL.
host: The IPv4 address that the application should listen on. Defaults to the shiny.host option, if set, or "127.0.0.1" if not. See Details.
workerId: Can generally be ignored. Exists to help some editions of Shiny Server Pro route requests to the correct process.
quiet: Should Shiny status messages be shown? Defaults to FALSE.
display.mode: The mode in which to display the application. If set to the value "showcase", shows application code and metadata from a DESCRIPTION file in the application directory alongside the application. If set to "normal"

Details

The host parameter was introduced in Shiny 0.9.0. Its default value of "127.0.0.1" means that, contrary to previous versions of Shiny, only the current machine can access locally hosted Shiny apps. To allow other clients to connect, use the value "0.0.0.0" instead (which was the value that was hard-coded into Shiny in 0.8.0 and earlier).

Examples

# Start app in the current working directory
runApp()

# Start app in a subdirectory called myapp
runApp("myapp")

## Only run this example in interactive R sessions
if (interactive()) {
  # Apps can be run without a server.r and ui.r file
  runApp(list(
    ui = bootstrapPage(
      numericInput('n', 'Number of obs', 100),
      plotOutput('plot')
    ),
    server = function(input, output) {
      output$plot <- renderPlot({ hist(runif(input$n)) })
    }
  ))


  # Running a Shiny app object
  app <- shinyApp(
    ui = bootstrapPage(
      numericInput('n', 'Number of obs', 100),
      plotOutput('plot')
    ),
    server = function(input, output) {
      output$plot <- renderPlot({ hist(runif(input$n)) })
    }
  )
  runApp(app)
}
