tajima.K: Calculate Tajima's K index of divergence
Description
Calculates Tajima's K index of divergence.
Usage
tajima.K(DNAbin, prop = TRUE)
Arguments
DNAbin
An object of class `DNAbin'.
prop
Logical. Should the function report the number of substitutions
per nucleotide? Default of TRUE.
Value
A vector of length 1. If prop = FALSE, the mean number of
substitutions between any two sequences is returned. If prop = TRUE
(the default), this number is returned as the mean number of substitutions
per nucleotide (i.e. the above divided by the length of the sequences).
