Hi,
I am having problems creating a pdf file of a lattice graph. Things work
fine for a single image, but I am having trouble using the commands in a
loop. To illustrate by example
This works with both ps and pdf files.
dat = list(x= 1:10, y = 1:10)
trellis.device(postscript, file = "/d1/pocernic/test.ps")
xyplot(y~x, data = dat)
dev.off()
This does not. It produces a very small, non working output file.
for(i in 1:1){
trellis.device(postscript, file = "/d1/pocernic/test.ps")
xyplot(y~x, data = dat)
dev.off()
}
Really, I would like something like this to produce a large, appended file
made from different large datasets. This doesn't work either.
trellis.device(postscript, file = "/d1/pocernic/test.ps", onefile =
TRUE)
for(i in 1:5){
xyplot(y~x, data = dat)
}
dev.off()
Any thoughts would be welcomed.
