chooseCellwidth function
Description
A function to help choose the cell width (the parameter "cellwidth" in lgcpPredictSpatialPlusPars, for example) prior to setting up the FFT grid, before an MCMC run.
Usage
chooseCellwidth(obj, cwinit)
Arguments
obj |
an object of class ppp, stppp, SpatialPolygonsDataFrame, or owin |
cwinit |
the cell width |
Details
Ideally this function should be used after having made a preliminary guess at the parameters of the latent field.The idea is to run chooseCellwidth several times, adjusting the parameter "cwinit" so as to balance available computational resources with output grid size.
Value
produces a plot of the observation window and computational grid.
