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.
