\title{Maxima and Minima}
\description{
  Returns the (parallel) maxima and minima of the input values.
}
\usage{
max(\dots, na.rm=FALSE)
min(\dots, na.rm=FALSE)

pmax(\dots, na.rm=FALSE)
pmin(\dots, na.rm=FALSE)
}
\arguments{
  \item{\dots}{numeric arguments.}
  \item{na.rm}{a logical indicating whether missing values should be
    removed.}
}
\value{
  \code{max} and \code{min} return the maximum or minimum of all the
  values present in their arguments, as \code{\link{double}}.
  If \code{na.rm} is \code{FALSE} an \code{NA} value in any of the
  arguments will cause a value of \code{NA} to be returned, otherwise
  \code{NA} values are ignored.

  \code{pmax} and \code{pmin} take several vectors as arguments and
  return a single vector giving the parallel maxima (or minima) of the
  vectors.  The first element of the result is the maximum (minimum) of
  the first elements of all the arguments, the second element of the
  result is the maximum (minimum) of the second elements of all the
  arguments and so on.  Shorter vectors are recycled if necessary.  If
  \code{na.rm} is \code{FALSE}, \code{NA} values in the input vectors
  will produce \code{NA} values in the output.  If \code{na.rm} is
  \code{TRUE}, \code{NA} values are ignored.
  \code{\link{attributes}} (such as \code{\link{names}} or
  \code{\link{dim}}) are transferred from the first argument (if applicable).
