[R-sig-Geo] Problem with lm.morantest

[buczkowski at delta.sggw.waw.pl]

Hello

I have a map of polygons in shapefile and a database in Access with
several 
attributes of the polygons from the shapefile. On data from the database I

am doing linear regression using function lm(). I would like to check 
whether there is spatial correlation in regresssion residuals. I loaded 
polygons using maptools, created a neighbor list using poly2nb() and then

spatial weights using nb2listw(). I made regression on data from the 
database (not from shapefile) and wanted to use lm.morantest() to
calculate 
Moran's I, and there the following error appeared "Error in 
lm.morantest(wmoddef, def_w, zero.policy = TRUE, alternative = "greater", 
:
        objects of different length" )

I realize that this is because the lists of polygons from shapefile and
records from regression are different. I was trying to match them by
sorting them in the same order but it didn't work. My question is how can
I conduct my analysis so the neighbor list and residuals from regression
would match each other in lm.morantest? 

Thanks in advance for your help

With best Christmas and New Year wishes
