fftinterpolate.fromXYZ: interpolate.fromXYZ function
Description
This method performs interpolation within the function fftgrid for fromXYZ objects.
Usage
## S3 method for class 'fromXYZ':
fftinterpolate(spatial, mcens, ncens, ext, ...)
Arguments
spatial
objects of class spatialAtRisk
mcens
x-coordinates of interpolation grid in extended space
ncens
y-coordinates of interpolation grid in extended space
ext
integer multiple by which grid should be extended, default is 2. Generally this will not need to be altered, but if the spatial correlation decays slowly, increasing 'ext' may be necessary.
