Don't do that; instead, use the device functions directly. For example,

pdf(file = "test.pdf")
print(test)
dev.off()

Multiple page support depends on the device, e.g. pdf() does, jpeg()
doesn't. Look at the respective help pages for details (and ?Devices
for an overview). Also look at ?trellis.device for pertinent comments.
