[R-sig-Geo] Creating Spatial Weight Matrices with Large Data

[Chanda Chiseni]

I am currently working with a census data that has about 758 000
individuals. I am trying to create a spatial weight matrix using the X-Y
coordinates for their place of birth . However, i am running into problems
when I try to create the nb type weights matrix using the poly2nb, R is
taking super long and after running for a long time it crushes. I have
increased R's memory size to about 80000 but this is still not working.

Is there a way i can get around this problem? If anyone has any ideas on
how i can create a spatial weight matrix for such a large data set please
help.

Kind Regards,
