\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"))
}
\arguments{
  \item{appDir}{The directory of the application. Should
  contain \code{server.R}, plus, either \code{ui.R} or a
  \code{www} directory that contains the file
  \code{index.html}. Defaults to the working directory.}

  \item{port}{The TCP port that the application should
  listen on. Defaults to choosing a random port.}

  \item{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.}

  \item{host}{The IPv4 address that the application should
  listen on. Defaults to the \code{shiny.host} option, if
  set, or \code{"127.0.0.1"} if not. See Details.}

  \item{workerId}{Can generally be ignored. Exists to help
  some editions of Shiny Server Pro route requests to the
  correct process.}

  \item{quiet}{Should Shiny status messages be shown?
  Defaults to FALSE.}

  \item{display.mode}{The mode in which to display the
  application. If set to the value \code{"showcase"}, shows
  application code and metadata from a \code{DESCRIPTION}
  file in the application directory alongside the
  application. If set to \code{"normal"}, displays the
  application normally.  Defaults to \code{"auto"}, which
  displays the application in the mode given in its
  \code{DESCRIPTION} file, if any.}
}
\description{
Runs a Shiny application. This function normally does not return; interrupt
R to stop the application (usually by pressing Ctrl+C or Esc).
}
\details{
The host parameter was introduced in Shiny 0.9.0. Its default value of
\code{"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 \code{"0.0.0.0"} instead (which was the
value that was hard-coded into Shiny in 0.8.0 and earlier).

\dontrun{
# 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

    numericInput('n', 'Number of obs', 100),
