clip.infline {spatstat.geom}

Intersect Infinite Straight Lines with a Window

Description

Take the intersection between a set of infinite straight lines and a window, yielding a set of line segments.

Usage

clip.infline(L, win)

Arguments

L

Object of class "infline" specifying a set of infinite straight lines in the plane.

win

Window (object of class "owin").

Details

This function computes the intersection between a set of infinite straight lines in the plane (stored in an object L of class "infline" created by the function infline) and a window win. The result is a pattern of line segments. Each line segment carries a mark indicating which line it belongs to.

Value

A line segment pattern (object of class "psp") with a single column of marks.
