Run Shiny Example Applications — runExample

v1.7.4|Source: R/runapp.R

Description

Launch Shiny example applications, and optionally, your system's web browser.

runExample(
  example = NA,
  port = getOption("shiny.port"),
  launch.browser = getOption("shiny.launch.browser", interactive()),
  host = getOption("shiny.host", "127.0.0.1"),
  display.mode = c("auto", "normal", "showcase")
)

Arguments

example: The name of the example to run, or NA (the default) to list the available examples.
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 between 3000:8000, excluding ports that are blocked by Google Chrome for being considered unsafe: 3659, 4045, 5060, 5061, 6000, 6566, 6665:6669 and 6697. Up to twenty random ports will be tried.
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.
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.
display.mode: The mode in which to display the example. Defaults to showcase, but may be set to normal to see the example without code or commentary.
