rdpp: Simulation of a Determinantal Point Process

Description

Generates simulated realisations from a determinantal point process.

Usage

rdpp(eig, index, basis = "fourierbasis",
       window = boxx(rep(list(0:1), ncol(index))),
       reject_max = 10000, progress = 0, debug = FALSE, …)

Arguments

eig

vector of values between 0 and 1 specifying the non-zero eigenvalues for the process.

index

data.frame or matrix (or something acceptable to as.matrix) specifying indices of the basis functions.

basis

character string giving the name of the basis.

window

window (of class "owin", "box3" or "boxx") giving the domain of the point process.

reject_max

integer giving the maximal number of trials for rejection sampling.

progress

integer giving the interval for making a progress report. The value zero turns reporting off.

debug

logical value indicating whether debug informationb should be outputted.

…

Ignored.

Examples

# NOT RUN {
index <- expand.grid(-2:2,-2:2)
eig <- exp(-rowSums(index^2))
X <- rdpp(eig, index)
X
## To simulate a det. projection p. p. with the given indices set eig=1:
XX <- rdpp(1, index)
XX
# }
