shiny (version 0.8.0)

runApp: Run Shiny Application

Description

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 = NULL,
    launch.browser = getOption("shiny.launch.browser", interactive()),
    workerId = "")

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. Defaults to the working directory.

port

The TCP port that the application should listen on. Defaults to choosing 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.

workerId

Can generally be ignored. Exists to help some editions of Shiny Server Pro route requests to the correct process.

Examples

# Start app in the current working directory
runApp()

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


# 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)) })
  }
))
