Thanks Uwe, you are right! The reason why it works fine now might be that the borders switch of the rect() function was set to "white" rather than NA when I sent my initial request. This obviously led to drawing of white borders that overlaid some of the tiny blue or red rectangles.
However, it is still suspicious to me that the screen output looks quite different from the plot in the pdf. Thanks all for your great help!

Unfortunately this does not help. In that case, we need a reproducible example. Uwe Ligges Kristian Am 17.04.2012 um 14:18 schrieb Petr PIKAL: Hi 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? I am not sure if it has something to do with dingbats but you could try it. Set useDingbats=FALSE in you pdf call.
