How to handle NA-values in raster-based Geary´s C test?
...st does not contain this option. The problem is that
geary.test needs an nb argument for which I cannot perform for example
nb<-ifelse(value, nb, NA), because it would change the nb-format to a
list-format.
Is there a way to ignore NA-values in geary.test? Or how can I set NA
values in a neigbors (nb) list?
Thank you very much,
Kerstin

Is there an implementation of a reasonable k-nearest neighbor finder
already in one of the packages?
