[R-sig-Geo] ordering of data in polygons shapefile

[Franziska Schulze]

Hallo,

I still have another question:

I have a polygon shapefile and I want to use it in order to construct my 
neighbors object and listw object to perform spatial econometric tests 
and to estimate a spatial model. The problem ist that the regions in my 
shapefile are not ordered as they should be in order to match with the 
other variables. Therefore, my question is whether it is possible to 
order a spatial polygons data frame with respect to one of its 
attributes. (The attribute is a region id number which has to ordered in 
increasing order.)

Thanks in advance!
