Saving lattice plot as a PDF

Hi there,
I need to save a series of lattice plots as a PDF,
this is my code so far:
windows(height=8,width=6)
plot.new()
library('grid')
lattice.options(layout.heights=list(top.padding=list(x=0.15,
units="inches")))
print(plot1, split=c(1,1,2,3), more=TRUE)
print(plot2, split=c(1,2,2,3), more=TRUE)
print(plot3, split=c(1,3,2,3), more=TRUE)
print(plot4, split=c(2,1,2,3), more=TRUE)
print(plot5, split=c(2,2,2,3), more=TRUE)
print(plot6, split=c(2,3,2,3), more=FALSE)
ltext(grid.locator(), label='text', cex=1.3)
ltext(grid.locator(), label='text', cex=1.3)
And when I open the PDF created I see "text" at the
bottom of may layout, even though I placed it at the
top of the sheet.. If I save it as a metafile of PNG
the layoout is correct.
I suspect the ``native'' coordinate system (which is all ltext() will
know about) is different for PDF. The following might work as
alternative for the ltext calls.
grid.text(label = "text",
cex = 1.3,
vp = do.call(viewport, grid.locator(unit="npc")))
