Dear ListeRs,
Since I normally produce output by Sweave, I never had to care about pixel
resolution. Now someone asked me for 600dpi tiffs of lattice.
I did not find an easy way to simply scale a tiff-image that looks good in
default display. See example below.
Dieter
library(lattice)
p = xyplot(Sepal.Length + Sepal.Width ~ Petal.Length + Petal.Width |
Species,
data = iris)
# looks good, but low resolution
trellis.device("tiff",file="a.tif")
print(p)
dev.off()
# do I really have to scale all fonts to get this right?
trellis.device("tiff",file="a1.tif",res=600,width=6000,height=4000)
print(p)
dev.off()
