These functions compute average trees or consensus trees by various criteria.
averageTree(trees, start=NULL, method="quadratic.path.difference",
   tol=1e-12, quiet=FALSE, ...)
ls.consensus(trees, start=NULL, tol=1e-12, quiet=FALSE, ...)
minTreeDist(tree, trees, method="quadratic.path.difference", ...)object of class "multiPhylo".
object of class "phylo". For minTreeDist the tree on which to find the edge lengths that minimize the distance to the phylogenies in trees.
starting tree for optimization.
distance criterion for minimization. Options are "symmetric.difference", "branch.score.difference", "path.difference", and "quadratic.path.difference".
tolerance value for optimization.
logical value indicating whether to run "quietly" or not.
other arguments to be passed internally.
An object of class "phylo" with edge lengths.
