hello.
Need, plotting in pdf, a result of an interpolation SpatialGrid and
additionally some sites above, but with the following statement:

*pol <- list("sp.polygons", pol, fill="transparent")
test.layout <- list(pol)

spplot(test1["var1.pred"], AXES = TRUE,scale= TRUE,
col.regions=bpy.colors(20),xlab="E-O",ylab="N-S",scales=list(draw=T),sp.layout
=test.layout)*



 Something happens and a blue spot print, or print the below sites, that
would fail to be ideal printing.

thanks for your answers and help
