rpoisppx
Generate Poisson Point Pattern in Any Dimensions
Generate a random multi-dimensional point pattern using the homogeneous Poisson process.
Usage
rpoisppx(lambda, domain, nsim=1, drop=TRUE)Arguments
- lambda
Intensity of the Poisson process. A single positive number.
- domain
Multi-dimensional box in which the process should be generated. An object of class
"boxx".- nsim
Number of simulated realisations to be generated.
- drop
Logical. If
nsim=1anddrop=TRUE(the default), the result will be a point pattern, rather than a list containing a single point pattern.
Details
This function generates a realisation
of the homogeneous Poisson process in multi dimensions,
with intensity lambda (points per unit volume).
The realisation is generated inside the multi-dimensional region
domain which currently must be a rectangular box (object of
class "boxx").
Value
If nsim = 1 and drop=TRUE,
a point pattern (an object of class "ppx").
If nsim > 1 or drop=FALSE, a list of such point patterns.
Note
The intensity lambda is the expected number of points
per unit volume.
