\title{Batch Execution of R}
\description{Run \R non-interactively with input from \code{infile} and
  send output (stdout/stderr) to another file.}
\usage{
R CMD BATCH [options] infile [outfile]
}
\arguments{
  \item{infile}{the name of a file with \R code to be executed.}
  \item{options}{a list of \R command line options, e.g., for setting the
    amount of memory available and controlling the load/save process.
    If \code{infile} starts with a \samp{-}, use \samp{--} as the final
    option.  The default options are \samp{--restore --save --no-readline}.}
  \item{outfile}{the name of a file to which to write output.  If not
    given, the name used is that of \code{infile}, with a possible
    \file{.R} extension stripped, and \file{.Rout} appended.}
}
\details{
  Use \code{R CMD BATCH --help} to be reminded of the usage.

  By default, the input commands are printed along with the output.  To
  suppress this behavior, add \code{options(echo = FALSE)} at the
  beginning of \code{infile}.

  The \code{infile} can have end of line marked by LF or CRLF (but not
  just CR), and files with an incomplete last line (missing end of line
  (EOL) mark) are processed correctly.

  Using \code{R CMD BATCH} sets the GUI to \code{"none"}, so none of
  \code{\link[graphics]{x11}}, \code{\link[graphics]{jpeg}}
  and \code{\link[graphics]{png}} are available.
}
\note{
  Unlike \code{Splus BATCH}, this does not run the \R process in the
  background.  In most shells,
  \code{R CMD BATCH [options] infile [outfile] &}
  will do so.
