[R-sig-Geo] Need help in creating a grid

[Bernd Vogelgesang]

Hi,
just found that some days ago. No Idea if that is what you meant or need.

bb <- bbox(spdf)
cs <- c(0.1,0.1)  # cell size
cc <- bb[, 1] + (cs/2)  # cell offset
cd <- ceiling(diff(t(bb))/cs)  # number of cells per direction
grd <- GridTopology(cellcentre.offset=cc, cellsize=cs, cells.dim=cd)
sp_grd <- SpatialGridDataFrame(grd,
                            data=data.frame(id=1:prod(cd)))

Cheers
Bernd
