\title{Relational Operators}
\description{
  Binary operators which allow the comparison of values in vectors.
}
\usage{
x < y
x > y
x <= y
x >= y
x == y
x != y
}
\value{
  A vector of logicals indicating the result of the element by element
  comparison.  The elements of shorter vectors are recycled as
  necessary.

  Objects such as arrays or time-series can be compared this way
  provided they are conformable.
}
\note{
 Don't use \code{==} and \code{!=} for tests, such as in \code{if}
  expressions, where you must get a single \code{TRUE} or
  \code{FALSE}.  Unless you are absolutely sure that nothing unusual
  can happen, you should use the \code{\link{identical}} function
  instead.
}
\examples{
x <- rnorm(20)
x < 1
x[x > 0]
