\name{gcommandline}
\alias{gcommandline}
\title{A command line interface}
\description{
This constructs a simple command line interface for R
}
\usage{
gcommandline(command = "", assignto = NULL, useGUI = TRUE,
useConsole = FALSE, prompt = getOption("prompt"), width = 500,
height = 0.6 * width, container = NULL, ...,toolkit =
guiToolkit())
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{command}{Initial command to evalues }
\item{assignto}{Assigns output to this variable is non-NULL}
\item{useGUI}{Is result also printed to GUI. Use FALSE to get
text-only instance}
\item{useConsole}{Is result also printed to console?}
\item{prompt}{Prompt to use}
\item{width}{Width of widget in pixels}
\item{height}{Height of widget in pixels}
\item{container}{Optional container to attach to}
\item{\dots}{Ignored for now}
\item{toolkit}{Which GUI toolkit to use}
}
\details{
Additional commands can be added programmatically with the
\code{svalue<-} method. The The value assigned is a string containing
the command. If it has a \code{names} attribute, this is taken as the
variable name to assign the output to.
The \code{svalue} method returns the command history.
The \code{"["} method can be used to retrieve the command history as well.
