Hi,
What I want to do is plot grid and plot points with Z
values over them with spplot. I have a
SpatialGridDataframe and a SpatialPointsDataframe. The
closest i get is:
> bla=list("sp.grid", a["var1.pred"])
> spplot(layer["AGOUTIS_DAY"], sp.layout=bla)
But then i get a completely black background. I was
wondering if there is an other way to let the panel
function sp.grid plot properly
I would have expected some syntax like the normal plot:
> spplot(a["var1.pred"])
> spplot(layer["AGOUTIS_DAY"], add=TRUE)
But that doesn't work either. What is the proper way to
achieve this assuming it is possible
Thanks
Bart
PS I'm using the sp and gstat libraries with R 2.5.1 on
Ubuntu linux
