.tipToRoot | R Documentation |

These hidden functions are utils for adephylo, used by other functions.
Regular users can use them as well, but no validity checks are performed for
the arguments: speed is here favored over safety. Most of these functions
handle trees inheriting phylo4 class.

.tipToRoot(x, tip, root, include.root = FALSE)

`x` |
A valid tree of class phylo4. |

`tip` |
An integer identifying a tip by its numbers. |

`root` |
An integer identifying the root of the tree by its number. |

`include.root` |
a logical stating whether the root must be included as a node of the path from tip to root (TRUE), or not (FALSE, default). |

`.tipToRoot`

finds the set of nodes between a tip and the root of a
tree.

`.tipToRoot`

: a vector of named integers identifying nodes.
