?dnearneigh in spdep package is the one I can think of.

Hi,
(As an exercise)I am trying to create a SpatialPolygons object from n*n
grid. By reading the material (from vignette{'sp'), I managed to convert
grid to polygons. Now I would like plot this polygons, and here is what
I have done so far:
Step1: Create a 9*9 grid
n<-9 # number of cells in ea

Hello,
I loaded a .shp-file and used a subset command while converting it
into a polygon to eliminate certain regions:
map.kreise<-readShapePoly("vg250krs",IDvar="KRS_ID",verbos=TRUE)
map.kreise.boden <-polygons(map.kreise)[x$BODENSEE==0]
Now I want to save the new object map.kreise.boden as a s
