Finding the right settings in lattice is a bit of intelligent guesswork. Here my sequence: 0) show.settings() # rather incomplete 1) str(trellis.par.get()) # names are quite rational, so this is 80% success 2) browse Deepayan's book examples http://lmdvr.r-forge.r-project.org/figures/figures.html After you got the right settings, keep these well wrapped for further use, for example by defining you own default theme. I noted your PrimaryColor which made the example less self-consistant. Check RColorBrewer and latticeExtra for a more standardize approach.
