Hi All, Does anyone knows what exactly "cuts=some number" (say 15) does in lattice's levelplot(). I doubt this but does it uses cut() internally, something like cut(z, 15)? Thanks, Gurmeet [[alternative HTML version deleted]]

Hi, I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure 13.7) . However instead of using a contour plot as a panel for the wireframe I want to use a levelplot. Can somebody help me with this? Thanks in advance for any help, Kind regards, Anton Bossenbroek
