getSisters(tree, node, mode=c("number","label"))

Arguments

tree	object of class "phylo".
node	a node number, tip number, node label, or tip label.
mode	an optional string indicating whether to return the node or tip number(s) or the node or tip label(s), if applicable.

This function takes a tree and node or tip number of label and returns the number or label of the sister or sisters to that node or tip.

Value

If mode="number" this function returns an integer or vector containing the node number of numbers of the sister node or tip.
