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
