shiny (version 0.9.1)

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()),
  host = getOption("shiny.host", "127.0.0.1"), workerId = "",
  quiet = FALSE, display.mode = c("auto", "normal", "showcase"))

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")


# 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)) })
  }
))
