Hi,
If you are curious you might like to try a highly experimental Grid
function I wrote some time ago,
library(grid)
source("http://gridextra.googlecode.com/svn/trunk/R/patternGrob.r";)
grid.newpage()
grid.pattern(x=seq(1/6, 5/6, length=6), width=unit(1/8,"npc"),
height=unit(0.5,"npc"),
motif.width=unit(10, "mm"), pattern=c(1:6),
orientation=45, motif.alpha=0.5,
motif.cex=c(1, 0.5), motif.col=1:2, motif.fill=NA,
gp=gpar(fill="blue", lwd=2, alpha=0.5), clip=T)
If you really insist on using shading patterns despite Greg's sound
advice, it might give you some inspiration.
HTH,
baptiste
