Run Shiny Application

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


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.
host The IPv4 address that the application should listen on. Defaults to the option, if set, or "" 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", displays the application normally. Defaults to "auto", which displays the application in the mode given in its DESCRIPTION file, if any.

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).


The host parameter was introduced in Shiny 0.9.0. Its default value of "" 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 "" instead (which was the value that was hard-coded into Shiny in 0.8.0 and earlier).
