Hello list members, i'd like to calculate the Moran I on a large dataset, a 8640x3432 grid of values.
When i try to create the neighbours list with the cell2nb function, on such a scale, R works for several hours and seems to crash. I'm using the last version (2.13), 64 bits, on a mac pro with 4go of memory. I think that i'm doing it wrong :-) I'd like to use a "moving window" weight matrix instead of a full scale one, but i was not lucky enough to find a solution in the docs. Thanks for any help, Laurent -- Laurent Jégou Cartographe et enseignant UTM - Dépt.
