R help - Nov 2009 - Trellis settings get lost when printing to pdf

Hi all,

 

I've got some problems when changing the trellis settings for the lattice
plots. The plots look exactly as I want them to when calling show.settings() as
well as when plotting them in the graphical window. But when printing to a pdf
file, none of the settings are used!? Does anyone know what might have happened?
Because the when changing the trellis settings, these should remain in the new
state until you close R right..?

 

# Change settings for the boxplot appearance
new.dot=trellis.par.get("box.dot")
new.rectangle=trellis.par.get("box.rectangle")
new.umbrella=trellis.par.get("box.umbrella")
new.symbol=trellis.par.get("plot.symbol")
new.strip.background=trellis.par.get("strip.background")
new.strip.shingle=trellis.par.get("strip.shingle")
new.dot$pch="|"
new.dot$col="black"
new.rectangle$col="black"
new.rectangle$fill="grey65"
new.umbrella$col="black"
new.umbrella$lty=1 # Continous line, not dotted
new.symbol$col="black"
new.strip.background$col="grey87" # Background colour in the upper
label
new.strip.shingle$col="black" # Border colour around the upper label
trellis.par.set(box.dot=new.dot, box.rectangle=new.rectangle,
box.umbrella=new.umbrella, plot.symbol=new.symbol,
strip.background=new.strip.background, strip.shingle=new.strip.shingle)

 

Best regards,

 

Joel

Did you make the changes before or after starting the device:

library(lattice)
## before doesn't change the settings on the device:
trellis.par.set(plot.symbol = list(col = "red"))
trellis.device(pdf, file = "tmp.pdf")
xyplot(1 ~ 1)
dev.off()

## after does
trellis.device(pdf, file = "tmp.pdf")
trellis.par.set(plot.symbol = list(col = "red"))
xyplot(1 ~ 1)
dev.off()

I never do things like this, though. I would suggest creating a theme
instead and supplying it to xyplot (or whatever plot you're using)
using par.settings:

my.theme <- list(plot.symbol = list(col = "red"))
trellis.device(pdf, file = "tmp.pdf")
xyplot(1 ~ 1, par.settings = my.theme)
dev.off()

HTH,
