OK will check out these resources. The original link made it seem like everyone is waiting for someone else to go through the code and figure out what it is doing.
If you use package 'akima' (which I use) the pdf I linked to describes the algoritms (without detail) and cites sources.
Edit: Scrub that. I just realised that akima passes on the interpolations to the contour function you linked to. I don't know if the interpolation method is what you're after, but it can't hurt to look at the package info, I suppose.

Did you try stackoverflow.com or the R help group?

Draws contour lines for the desired levels. There is currently no documentation about the algorithm. The source code is in `$RHOME/src/main/plot.c'.

I need to know what algorithm R is using for contour plots. How do I find this out?
