Objet: Transparency and trellis device
Dear R-users,
I am trying to produce trellis (png, or jpeg) graphs with transparent
background, but I cannot manage to make that happen. I tried to play around
with themes but to no avail. Any advise on the following example will be
greatly appreciated:
Thank you
Sebastien

library(lattice)
df <- data.frame(a=rep(1:4,4), b=rep(1:4,4), c=rep(1:4,each=4))
settings <- standard.theme()
settings <- modifyList(settings,
list(background=list(alpha=1,
col="transparent")))
str(settings)
trellis.device(png,
file="test.png",
theme=settings)
myplot<-xyplot(b~a|c, data=df)
print(myplot)
dev.off()
