Intersect Infinite Straight Lines with a Window
Take the intersection between a set of infinite straight lines and a window, yielding a set of line segments.
clip.infline(L, win)

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

To divide a window into pieces using infinite lines,
use chop.tess.
L <- infline(p=1:3, theta=pi/4) W <- square(4) clip.infline(L, W)
