rpoisppx {spatstat} | R Documentation |
Generate a random multi-dimensional point pattern using the homogeneous Poisson process.
rpoisppx(lambda, domain, nsim=1, drop=TRUE)
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 |
nsim |
Number of simulated realisations to be generated. |
drop |
Logical. If |
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"
).
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.
The intensity lambda
is the expected number of points
per unit volume.
