Description

Simulating a conditional/unconditional Gaussian random field via kriging and circulant embedding

Usage

1
krigeSimCE(formula, data, newdata, model, n = 1, ext = 2)

Arguments

formula

the formula of the kriging predictor

data

spatial data frame that conditions the simulation

newdata

locations in space where the Gaussian random field shall be simulated

model

a vgm model that defines the spatial covariance structure

n

number of simulations

ext

extension factor of the circulant embedding, defaults to 2

Value

A spatial data frame as defined in newdata with n simulations.
