Value

A vector with the tip names of extant or extinct species in the tree.

Details

The function getExtant takes a tree as input and returns a vector containing the names of all the tips that have a height above the root that is equal (to a degree of numerical precision determined by tol) to the height of the highest tip. These tips are presumed to be "extant."

getExtinct returns the complement.
