SortTree() sorts each node into a consistent order, so that node rotation
does not obscure similarities between similar trees.
SortTree(tree, how = "cladesize", order = TipLabels(tree)) # S3 method for phylo SortTree(tree, how = "cladesize", order = TipLabels(tree)) # S3 method for list SortTree(tree, how = "cladesize", order = TipLabels(tree[])) # S3 method for multiPhylo SortTree(tree, how = "cladesize", order = TipLabels(tree[]))
One or more trees of class
phylo, optionally as a list
Character vector specifying sort method:
"Cladesize" rotates each node such that the larger clade is first,
thus appearing lower when plotted;
"TipLabels" rotates nodes such that labels listed sooner in
are listed first, and thus plot lower.
Character vector listing tip labels in sequence they should
appear on tree. Clades containing a taxon earlier in this list will be listed
sooner and thus plot lower on a tree. Taxa not listed in
order will be
treated as if they were last in the list.
SortTree() returns tree in the format of
tree, with each node
in each tree sorted
At each node, clades will be listed in
tree[["edge"]] in decreasing size
Clades that contain the same number of leaves are sorted in decreasing order of minimum leaf number, so (2, 3) will occur before (1, 4).
As trees are plotted from 'bottom up', the largest clades will 'sink' to the bottom of a plotted tree.
Preorder() also rearranges trees into a consistent shape,
based on the index of leaves.
