2. I'd like to produce a .png file with graphs without drawing them on
the screen.
I try:
png(filename = "Rplot.png", width = 480, height = 1024, pointsize = 12,
bg = "white");
trellis.device(device=getOption("png"),
color = FALSE,
bg = "white" );
xyplot.... [see above]
But I get the error message:
Error in trellis.device(device = getOption("png"), color = FALSE, bg = "white") :
couldn't find function "device.call"
Where's the problem?
Thare is no option "png". Look at the help for trellis.device to see what you should be using as a `device' argument: it even lists how to use the png() device.
I use R 1.7.0 and Windows NT 4.0 workstation.
