I am using lattice to make figures as pdfs:
trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE)

I need to specify some blank space on the left-hand margins (the
pages will be bound so we need about 0.5 inch)). I have tried a
number of solutions but none seems to work (e.g. par.set). Can
this be done when initiating the plotting device? Or is the some
other way that does not require me to manually move everything
over?

Michael,

I believe you can do this using print.trellis and setting the
position argument. E.g.

trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE)
xy <- xyplot(...)
print(xy, pos = c(0.10, 0, 1, 1))
dev.off()

Or if you want exactly 0.5 inches, something like ...

# may need
# library(grid)
trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE)
xy <- xyplot(1:10 ~ 1:10)
pushViewport(viewport(x=1,
                       width=unit(1, "npc") - unit(0.5, "inches"),
                       just="right"))
# to show region you're plotting in
# grid.rect(gp=gpar(col="grey"))
print(xy, newpage=FALSE)
popViewport()
dev.off()
