I need to use the Bhattacharyya distance metric to determine population separation.

Hi all, I'd like to add the Bhattacharyya method to the dist function. What is the best way to do this? I'm using R 1.9.0 and I was looking for the code that defines the already existing distances, but I didn't manage. As far as I understand, dist is defined in mva that is part of the stats package now, but where is the code? Than...

I am looking for packages that can run a branch-and-bound algorithm to maximize a distance measure (such as Bhattacharyya or Mahalanobis) on a set of features. I would like this to be learning algorithm independent, so that the method just looks at the features, and selects the subset of a user-defined size that maximizes a distance criteria such as those stated above. Can anyone give some suggestions? Alex Byrley...
