\title{Apply Vector Translation}
\description{
Applies a vector shift of the plane
to a geometrical object,
such as a point pattern or a window.
}
\usage{
shift(X, \dots)
}
\arguments{
\item{X}{Any suitable dataset representing a two-dimensional
object, such as a point pattern (object of class \code{"ppp"}),
or a window (object of class \code{"owin"}).}
\item{\dots}{Arguments determining the shift vector.}
}
\value{
Another object of the same type, representing the
result of applying the shift.
}
\details{
This is generic. Methods are provided for
point patterns (\code{\link{shift.ppp}})
and windows (\code{\link{shift.owin}}).
The object is translated by the vector \code{vec}.
