[R-sig-Geo] strip in spplot do not show

[Edzer Pebesma]

I browsed through the figures of Deepayan Sarkar's book on Lattice, and
found on http://lmdvr.r-forge.r-project.org/figures/figures.html figure
11.3, which seem to be what you need. Using his code, and building on
your example:

library(sp)
library(lattice)
data(meuse.grid)
coordinates(meuse.grid) <- c("x","y")
gridded(meuse.grid) <- TRUE
fullgrid(meuse.grid) <- TRUE
spplot(meuse.grid, zcol=c(1,2))
update(trellis.last.object(), layout = c(1, 1))[2]
