orisaved
Maximal or minimal amount of originality saved under optimal conditions
Description
computes the maximal or minimal amount of originality saved over all combinations of species
optimizing the amount of evolutionary history preserved. The originality of a species is measured
with the QE-based index.
Usage
orisaved(phyl, rate = 0.1, method = 1)
Arguments
phyl
rate
method
an object of class phylog
a real value (between 0 and 1) indicating how many species will be saved for
each calculation. For example, if the total number of species is 70 and ’rate =
0.1’ then the calculations will be done at a rate of 10 % i.e. for 0 (= 0 %), 7
(= 10 %), 14 (= 20 %), 21 (= 30 %), ..., 63 (= 90 %) and 70(= 100 %) species
saved. If ’rate = 0.5’ then the calculations will be done for only 0 (= 0 %), 35 (=
50 %) and 70(= 100 %) species saved.
an integer either 1 or 2 (see details).
Details
1 = maximum amount of originality saved 2 = minimum amount of originality saved
Value
Returns a numeric vector.
