locate.yeti {phytools}R Documentation

Locate a cryptic, recently extinct, or missing taxon on a tree


This function uses ML (or REML) to place a recently extinct, cryptic, or missing taxon on an ultrametric (i.e., time-calibrated) phylogeny.


locate.yeti(tree, X, ...)



an object of class "phylo".


a matrix with continuous character data.


optional arguments including: method ("ML" or "REML", defaults to "ML"); search ("heuristic" or "exhaustive", defaults to "heuristic"); constraint, a vector containing the daughter node numbers from tree$edge for each edge to try; plot a logical argument specifying whether or not to plot the likelihood profile on edges (defaults to FALSE); rotate a logical indicating whether or not to rotate the data based on the input tree; and quiet, which is logical and has an obvious interpretation.


Optimized tree as an object of class "phylo".
