Function for calculating pairwise Delta D and correlation between genetic differentiation (Delta D) and geographic distance

Description

This function calculates new pairwise genetic differentiation, Delta D (Gaggiotti OE, et al, 2018), as well as the correlation between genetic differentiation (Delta D) and geographic distance.

Usage

COR_DeltaDd(f, d, ncode, nrepet)

Arguments

f	A genetic data files, the format is genepop format.
d	Pairwise geographic distance for calculating correlations. If no actual geographic distance, d=NULL. If TRUE, the geographic distance should be a matrix that corresponds to the pairwise genetic differentiation matrix.
ncode	The coding type of your genetic data.
nrepet	Number of permutations.

Details

This function returns to lists of pairwise Delta D matrix, and a matrix of theorical geographical distance if d is NULL, as well as the correlation coefficient.

Value

PairwiseDeltaD	The pairwise genetic differentiation matrix (Delta D).
Dgeo	The pairwise geographical distance matrix.
CorDeltaDd	Pearson correlation coefficient between genetic differentiation (Delta D) and geographic distance.
