genFFTgrid: genFFTgrid function

In lgcp: Log-Gaussian Cox Process

genFFTgrid function

Description

A function to generate an FFT grid and associated quantities including cell dimensions, size of extended grid, centroids, cell area, cellInside matrix (a 0/1 matrix: is the centroid of the cell inside the observation window?)

Usage

genFFTgrid(study.region, M, N, ext, inclusion = "touching")

Arguments

study.region	an owin object
M	number of cells in x direction
N	number of cells in y direction
ext	multiplying constant: the size of the extended grid: ext*M by ext*N
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.

Value

a list
