fftgrid: fftgrid function

In lgcp: Log-Gaussian Cox Process

fftgrid function

Description

! As of lgcp version 0.9-5, this function is no longer used !

Usage

fftgrid(xyt, M, N, spatial, sigma, phi, model, covpars, inclusion = "touching")

Arguments

xyt	object of class stppp
M	number of centroids in x-direction
N	number of centroids in y-direction
spatial	an object of class spatialAtRisk
sigma	scaling paramter for spatial covariance function, see Brix and Diggle (2001)
phi	scaling paramter for spatial covariance function, see Brix and Diggle (2001)
model	correlation type see ?CovarianceFct
covpars	vector of additional parameters for certain classes of covariance function (eg Matern), these must be supplied in the order given in ?CovarianceFct
inclusion	criterion for cells being included into observation window. Either 'touching' or 'centroid'. The former includes all cells that touch the observation window, the latter includes all cells whose centroids are inside the observation window.

Details
