Depends on how motivated you are. Here's one solution. It will take some effort to get going and requires a few programming skills, but once set up you can repeat the process painlessly.

First, you need to use Apple's Keynote. The Keynote file format is a regular zipped directory containing an XML file and the various media (e.g. pdfs, pngs). The XML format is documented here:

http://developer.apple.com/appleapplications/keynote-apxl.html

Given that and some trial and error, one can write a python script (or similar) to take a folder of graphs that you output from R and convert them into a Keynote presentation.

If you don't want to use Keynote as your final format, you can export the file into a huge PDF or a PowerPoint file.

And if you get something working and are willing to share, I'm sure several people on the list would be interested in seeing a working script!


How you intend to keep your audience awake for a presentation of hundreds of graphs is another problem entirely. :)


Cheers,
Demitri
