\title{Rotate a Line Segment Pattern}
\description{
Rotates a line segment pattern
}
\usage{
\method{rotate}{psp}(X, angle=pi/2, \dots)
}
\arguments{
\item{X}{A line segment pattern (object of class \code{"psp"}).}
\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{"psp"} representing the
rotated line segment pattern.
}
\details{
The line segments 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 line segments carry marks, these are preserved.

Y <- rotate(X, pi/4)
