[R] Embedding Audio Files in Interactive Graphs

[Sam Ferguson]

Thanks for your reply Bruno.

No - as I said, I know how to do that - the movie15 and the  
multimedia package are basically the same, and it is relatively  
straightforward to get an audio file into a pdf with them. However,  
real interactivity is not easily achieved in latex IMO (as it's not  
its purpose). At least I'm hoping for a bit more flexibility.

R seems like a better place to do interactivity, and with the field  
of information visualisation pointing out that interactivity is a  
very useful element for investigation of data it seems that clicking  
around graphical displays may become more and more popular in time.  
In my field I'm interested in audio data, and so simple interactive  
visual and auditory displays would be great. A (very useful) start  
would be 5 separate waveform plots that would play their appropriate  
sounds when clicked. More complex figures could plot in a 2d space  
and allow selection of data points or ranges perhaps.

I love R for graphics and for Sweave though, and would like to use it  
if possible - ideally it would be to produce a figure that included  
the appropriate audiofiles and interactive scripts, which could then  
be incorporated into a latex document \includegraphics. However, from  
the deafening silence on this list it seems like I may be attempting  
to push a square block through a round hole unfortunately. Seems I am  
back to Matlab and handle graphics - but it won't do this properly  
either.

Cheers
Sam
