Description Usage Arguments Details Value Author(s) See Also Examples

Reports the ancestors of a given node. Now simply a wrapper for TreeTools::ListAncestors().

1	list.ancestors(parent, child, node)

`parent`	the 'parent' column of the edges property of a tree of class `phylo`;
`child`	the 'child' column of the edges property of a tree of class `phylo`;
`node`	the number of the node or tip whose ancestors are required.

To observe the number of a node or tip, use plot(tree); nodelabels(); tiplabels();

Returns a vector of the numbers of the nodes ancestral to the given node, including the root node.

phangorn:::Ancestors, a less efficient implementation on which this code is based.

  tree   <- ape::read.tree(text='(1, (2, (3, (4, 5))));')
  edge   <- tree$edge
  parent <- tree$edge[, 1]
  child  <- tree$edge[, 2]
  list.ancestors(parent, child, 4)
