While on this path you might also want to learn that it is different  
to do
   plot(1:10)
   dev.copy2pdf
compared to doing
   pdf()
   plot(1:10)
   dev.off()

The defaults for the different devices are sometimes slightly  
different. You can also generate postscript, png and svg from the  
command line.
