\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).
