Hi there

is it possible that pdfs generated using the pdf() function with default settings leads to loss of information? I was plotting copy number changes from Agilent 180k data in form of rectangles (rect()) while each rectangle represents one region of copy number change. When plotting into a pdf I noticed that some very small rectangles do not appear (even after extensive zooming) in the pdf using the pdf() function. But they do when writing the screen output into a pdf using the GUI. Does anyone have some advice on this how I can plot pdfs without losing information?

Best wishes

Kristian
