\usage{
is.equivalent(x, y, tollerance = .Machine$double.eps^0.5)
}
\arguments{
\item{x}{either a numeric vector, or a data.frame containing such vectors.}

\item{y}{either a numeric vector, or a data.frame containing such vectors.}

\item{tollerance}{numeric >= 0. Differences smaller than tolerance are not considered.}
}
\value{
logical TRUE if the two vectors are from the same equivalence class.
}
\description{
Checks if two vectors or two data frames are from the same equivalence class
}
\examples{
