R question

[bb113]

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?

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

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.

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.
