drawing order in spplot, sp.layout

Dear listers,
I am messing with spplot trying to get layers in the right order.
Basically I want a SpatialGridDataframe overlapped with a
SpatialPolygons object (actually a SpatialPolygonsDataFrame object).
The the data attribute of the SpatialGridDataFrame has 13 columns (12
months + the annual average of temperature). So, I expect 13 lattices
panels corresponding to each.
This gives:
addCh<-list("sp.polygons",chinaUTM47,border="grey50")
Patrick, I believe there's the option
addCh<-list("sp.polygons",chinaUTM47,col="grey50", first = FALSE)
that solves this. I can't find it really in the documentation, so
something's missing there for sure. Use col instead of border.

spplot(ChinaTempTT,col.regions=mypal,sp.layout=addCh,as.table=T) Unfortunately, in each panel: - the polygons are drawn first and then are covered by the the grid (the reverse of what I want to). Thus polygons are invisible. - the argument border="grey50" does not seems to used Any hint ? Patrick
