I suppose you could average the distance matrices, getting a distance matrix, and then apply hierarchical clustering... or threshold the average distance matrix at a sequence of values and compute connected components for each... that sounds like it's in the spirit of a "majority-rule consensus tree" though I don't know what that is.

A friend pointed out that a similar question remained unanswered in 2004. I wish to re-word my question: is anyone aware of a package / method to obtain a majority-rule consensus tree from x distance matrices ? Is anyone using R to generate phylogenetic trees with node support ? thanks for your time and consideration, Eric P.
