| rpoisline {spatstat} | R Documentation |
Generate a random pattern of line segments obtained from the Poisson line process.
rpoisline(lambda, win=owin())
lambda |
Intensity of the Poisson line process. A positive number. |
win |
Window in which to simulate the pattern.
An object of class "owin"
or something acceptable to as.owin.
Currently, the window must be a rectangle.

This algorithm generates a realisation
of the uniform Poisson line process, and clips it to the window
win.
Currently win must be a rectangle.
The argument lambda must be a positive number.
It controls the intensity of the process. The expected number of
lines intersecting a convex region of the plane is equal to
lambda times the perimeter length of the region.
The expected total length of the lines crossing a region of the plane
is equal to lambda * pi times the area of the region.
A line segment pattern (an object of class "psp").
