\title{Rotate a Point Pattern}
\description{
Rotates a point pattern
}
\usage{
\method{rotate}{ppp}(X, angle=pi/2, \dots)
}
\arguments{
\item{X}{A point pattern (object of class \code{"ppp"}).}
\item{angle}{Angle of rotation.}
\item{\dots}{Arguments passed to \code{\link{rotate.owin}} affecting
the handling of the observation window, if it is a binary pixel mask.}
}
\value{
Another object of class \code{"ppp"} representing the
rotated point pattern.
}
\details{
The points of the pattern, and the window of observation,
are rotated about the origin by the angle specified.
Angles are measured in
radians, anticlockwise. The default is to rotate the pattern 90 degrees
anticlockwise. If the points carry marks, these are preserved.
