R help - May 2007 - Partitioning a kde2d into equal probability areas

Hi,

I'd like to partition a 2d probability density function into regions of 
equal probability.  It is straightforward in the 1d case, like 
qnorm(seq(0,1,length=5)) but for 2d I'd need more constraints.

Any suggestions for how to approach this?  Is seems like a spatial 
sampling problem but I'm not sure where to look.

Thanks for your time,

Dave

Hi David,

This is an interesting question! I was wondering is the density function like?
What sort of partitions are you looking for?

Sorry I am not of much help, but this question perhaps better-defined?

Best,
Ranjan
