[R] Lattice and high-resolution tiffs

[r-help.20.trevva at spamgourmet.com]

Hi,

I am trying to produce high-resolution (600dpi+) TIFF figures for use
in a publication. Everything seems to work well when using the
"normal" R-graphics and the relative text size obtained is independent
of the output resolution. However, when I try and make lattice plots,
the relative size of the text labels changes when I adjust the
resolution - they become extremely small at high resolution. Some
sample code is attached below - as you will see, the text in the low
resolution plot is as expected, whilst that in the high-resolution is
there, but very very small.
I'm running R 2.9.1 on Windows - R.Version() info is contained at the
very bottom.

Any ideas?
Cheers,

Mark


Sample code
-----------

Depth <- equal.count(quakes$depth, number=8, overlap=.1)
p<- xyplot(lat ~ long | Depth, data = quakes)

tiff("Low res plot.tiff",width=155/25.4,height=155/25.4,units="in",res=72,pointsize=12,compression="none")
print(p)
dev.off()

tiff("High res plot.tiff",width=155/25.4,height=155/25.4,units="in",res=600,pointsize=12,compression="none")
print(p)
dev.off()
