 
Thank you for your post.
If I run:
trellis.dev(pdf, filename="junk.pdf')
plot(c(1:10)) 
dev.off()
  
I get the correct junk.pdf. 
But when I try to draw some fancy stuff using xyplot(...), then I just get a junk.pdf of 4kb only, and abode says ".. error, .. it has no page." If I remove dev.off(), then I can get correct junk.pdf after I close the R.
Any thoughts?
If you really need my codes, I can post. But there are maybe too many things going on my codes.

Perhaps if you post the rest of the code you are using, we might be
able to help - but trellis.dev(pdf, filename="'); ...; dev.off()
certainly works for me.
