Trellis barchart, column display order issue
...gure out how to get R to spool the graphs to a pdf file so I get all 30 graphs and I can save them for an appendix. I just want to be able to save all the graphs for future use, so I am not set on pdf or anything else. An example would be great! Thanks, Mike Michael J. Bock, PhD.

Suggestion for the posting guide
...example code that can be placed in the posting guide? Is it really a good idea to show people how to do this as we run the risk of someone sending a huge e-mail?

Lattice device page options-margins
...e pages will be bound so we need about 0.5 inch)). I have tried a number of solutions but none seems to work (e.g. par.set). Can this be done when initiating the plotting device? Or is the some other way that does not require me to manually move everything over? Michael J. Bock, PhD.

Text in lattice Graphics outside plot area
...ther get errors or "curious" looking plots. The option of last resort would be to explicitly plot each sample and add the text to each plot, but this does not take advantage of the multi-plot capabilities of lattice graphics.
