\title{Apply Vector Translation To Window}
\description{
  Applies a vector shift to a window
}
\usage{
 \method{shift}{owin}(X, vec=c(0,0), \dots)
}
\arguments{
  \item{X}{Window (object of class \code{"owin"}).}
  \item{vec}{Vector of length 2 representing a translation.}
  \item{\dots}{Ignored}
}
\value{
  Another window (of class \code{"owin"}) representing the
  result of applying the vector shift.
}
\details{
  The window is translated by the vector \code{vec}.
  This is a method for the generic function \code{\link{shift}}.
