Dest.Chao: A Measure of Genetic Differentiation

Description

This function calculates the measure of genetic differentiation Dest.Chao (Jost, 2008, p. 4022, eqn. 13) for each locus that has been examined, separately, as well as averaged over all loci.

Usage

Dest.Chao(tab)

Arguments

tab

A data table that equals the output of the function inputformat (see the section 'value' in the description of this function). A different input format can be used by transforming it using t

Value

• A list 'D.Chao.values' is returned and assigned to the workspace (.GlobalEnv). It comprises a data table and a single value.
• Dest.Chao.values.for.loci
  A data table comprising the value of genetic differentiation for each locus separately
• Mean.Dest.Chao.value
  The mean value of genetic differentiation over all loci
• The tables 'allelefrequency' and 'sample.sizes' returned from the function allelefreq are both additionally assigned to the workspace (.GlobalEnv). See allelefreq for further details of the function and its returned values. It is included in this package.

Details

• Details about the measure of genetic differentiation can be found in Jost (2008) and the references cited therein.
