rpoislinetess
Poisson Line Tessellation
Generate a tessellation delineated by the lines of the Poisson line process
Usage
rpoislinetess(lambda, win = owin())
Arguments
- 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 toas.owin
. Currently, the window must be a rectangle.
Details
This algorithm generates a realisation
of the uniform Poisson line process, and divides the window
win
into tiles separated by these lines.
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.
Value
A tessellation (object of class "tess"
).
Also has an attribute "lines"
containing the realisation of the
Poisson line process, as an object of class "infline"
.
See Also
rpoisline
to generate the lines only.
Examples
# NOT RUN {
X <- rpoislinetess(3)
plot(as.im(X), main="rpoislinetess(3)")
plot(X, add=TRUE)
# }
