When branch lengths in an ultrametric phylogenetic tree are expressed as divergence times, the total sum of branch
lengths in that tree expresses the amount of evolutionary history. The function randEH
calculates the amount of evolutionary history preserved when k random species out of n
original species are saved.
Usage
randEH(phyl, nbofsp, nbrep = 10)
Arguments
phyl
an object of class phylog
nbofsp
an integer indicating the number of species saved (k).
nbrep
an integer indicating the number of random sampling.
