[R] Embedding Audio Files in Interactive Graphs

[Sam Ferguson]

Hi R-ers,

I'm wondering if anyone has investigated a method for embedding audio  
files in R graphs (pdf format), and allowing their playback to be  
triggered interactively (by clicking on a graph element for instance).

I know how to do this in latex pdfs with the multimedia package, but  
it seems that R would provide a more appropriate platform for many  
reasons.

Thanks for any help you can provide.
