\title{Batch Execution of R}

\description{Run \R non-interactively with input from \code{infile} and

  send output (stdout/stderr) to another file.}

\usage{

\special{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 \option{--} as the final

    option.  The default options are \option{--restore --save}.}

  \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 \command{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}, or use option \option{--slave}.

  Files with an incomplete last line (no end of line mark) are

  accepted.

  A final expression \samp{proc.time()} will be executed after the input

  script unless the latter calls \code{\link{q}(runLast = FALSE)} or is aborted.

  This can be suppressed by the option \option{--no-timing}.

  Additional options can be set by the environment variable

  \env{R_BATCH_OPTIONS}: these come after \option{--restore --save}

  and before any options given on the command line.
