In fact plots saved as PDF have higher quality than the EMF format as  
PDF is the publishing standard, whereas EMF is restricted by the  
Windows GDI and its (im)precision. PDFs created by either the PDF  
device or the Quartz device in R are both precise vector formats  
without any loss of quality.

Anyway, this is not about the format, but probably about the tools  
you use. Note that MS tools cannot handle PDF well (they convert it  
to low-quality bitmaps), but then I hope would not use such tools for  
publication or presentation... (especially not on a Mac ;)).
