Dear Ulrich, please try the "at" argument of spplot; see the following
example on lattice::levelplot, for which spplot is a front-end:
xy = expand.grid(x=1:10,y=1:10)
xy$z = runif(100)
library(lattice)
levelplot(z~x+y,xy)
levelplot(z~x+y,xy,at=(0:10)/
Dear all,I try to plot a raster map with a correct colour key using spplot. But the minimum seems to be smaller than the data minimum in the colour key.
I use the following code:## Summary of raster map
> summary(slope.grid)Object of class SpatialGridDataFrameCoordinates:
min max
x
