Hi list,
Is there a package that covers the evaluation of spatial statistics on
images and not on point data? I've converted an image matrix to x, y
coordinates and a measurement value but evaluation with the package
spdep (not really designed for image data I suppose) is unworkable. Any
suggestions?
It depends what you are trying to do, also please consider re-posting on
the R-sig-geo list. Yes, constructing a neighbour list for a large image -
millions of points and thus potentially very many neighbours - is not what
spdep is dimensioned for. Advice will depend on your research problem.
Regards,
Koen
