Generate trivial trees

SingleTaxonTree() creates a phylogenetic "tree" that contains a single taxon. ZeroTaxonTree() creates an empty phylo object with zero leaves or edges.

Usage

SingleTaxonTree(label = "t1", lengths = NULL)

ZeroTaxonTree()

Arguments

label

a character vector specifying the label of the tip.

lengths

a numeric vector specifying the edge lengths of the tree.

Value

SingleTaxonTree() returns a phylo object containing a single tip with the specified label.

ZeroTaxonTree() returns an empty phylo object.
