[R] y-axis of lattice panels not printing to paper

[Pam Goodman]

Deepayan,
Thanks for the suggestions for changing the size of the screen devices/win.print. They did not work for me. 

Mea culpa, I neglected in my orinal email to say that it's just the vertical line of the y-axis that does not print, not the entire y-axis and associated labels. Tick marks, tick labels, and the y-axis label print nicely.  Hopefully, this information will help isolate the problem (?). 

Also, I should note that our office has the option of printing through our network to an HP laser printer or to a photocopier, and both of these options produce the same problem, no vertical line of the y-axis. Our default paper size, which I have been using, is 8.5x11 inches. 

Thanks again!

Pam

I have no idea what the problem is. Might it have something to do with paper
size? Does changing the size of your screen devices/win.print help?

I should mention that this is probably not a good way to print lattice graphs.
The settings for screen devices are not suitable for printing. I think there
are also more general issues with converting output of one device to another (I
don't understand all the details). In this situation, I would use 

trellis.device(pdf, file = "foo.pdf")
for(i in 1:50){
  print(histogram(~dbh|species.c, data=eval(parse(text=site.names.sort[i])), 
  breaks=c(0,seq(4,92,by=2)), main=site.names.sort[i], type="density"))
  }
dev.off()

and then print the PDF file.
