spplot with two rasters
I find it hard to imagine how you want to plot two raster files on top of each other. Do you want some form of transparency? If it is just one overlaying the other, you could use overlay to find out which cells in raster 1 to replace with those in raster 2 before plotting. -- Edzer

Hi,
Is it possible to plot two raster images using spplot() in a manner similar
to:
pts <- list("sp.points", points_file, pch = 4, col = "black", cex=0.5)
spplot(raster_file, zcol="elev.pred", sp.layout=list(pts))
Note that one of the raster images is an aerial photo, used only for context,
while the second one is one with interesting z-values. The second raster is
masked and thus does not cover the entire region.
Thanks,
Dylan
