\description{
\command{RMrotat} and \command{RMrotation} are
auxiliary space-time functions that create some rotation
\deqn{f(h, t) = s (\cos(\phi t) h_1 + \sin(\phi t) h_2) / \|h\|}
and
\deqn{f(h, t) = (\cos(\phi t) h_1 + \sin(\phi t) h_2,
- \sin(\phi t) h_1 + \cos(\phi t) h_2, t),}
respectively.
}
\usage{
RMrotat(speed, phi)
RMrotation(phi)
}
\arguments{
\item{speed}{real value \eqn{s} }
\item{phi}{angle}
}
\details{
\command{\link{RMrotat}} and \command{\link{RMrotation}} are
space-time models for
two-dimensional space.
}
\value{
\command{\link{RMrotat}} and \command{\link{RMrotation}} return an object of class \code{\link[=RMmodel-class]{RMmodel}}.
