One thread deals with a similar question (http://thread.gmane.org/gmane.comp.lang.r.mac/4086/focus=4103), but doesn't quite solve my problem.

But I need to be able to see the layout on the page as it will appear on the PDF so that I can work on getting it how I want it. There is no way to scroll down and see the bottom of the window, and I don't know of a way I can change the view of the quartz window without changing the actual size of the image. Any size greater than the default seven inches is not visible on the screen without resizing the window and distorting the proportion and changing the size.

The other solution is to make all the plots separately first and then put them on the one page, but I want to see the whole page so I can customise the margins etc. Is there a way to change the view of the quartz window without changing its size?

Yes, set the dpi to something lower than your actual screen - that will allow you to see the whole page even on a smaller screen, e.g.:

quartz(title="Fig.1",width=8.27,height=11.69, dpi=70)
