spplot(), SpatialGridDataFrame

Hi, I have a SpatialGridDataFrame and want to plot it with spplot(). Is it possible to plot only the grids that have a special value (eg. 312)?
fullgrid(x) = FALSE spplot(x[x$value == 312,"value"] Note that if fullgrid(x) is TRUE, x[rows,cols] would select on rows/cols, not on attribute values.
If it is not possible to do this with spplot() how would it be done with plot()?
I'd use image rather than plot; plot would use symbols instead of coloured squares. -- Edzer
Thanks, Ingo
