Spatial autocorrelation following Smouse and Pekall 1999

Description

Global spatial autocorrelation is a multivariate approach combining all loci into a single analysis. The autocorrelation coefficient r is calculated for each pairwise genetic distance pairs for all specified distance classes. For more information see Smouse and Peakall 1999, Peakall et a. 2003 and Smouse et al. 2008.

Usage

spautocor(gen.m, eucl.m, shuffle = FALSE, bins = 10)

Arguments

gen.m	a matrix of individual pairwise genetic distances. Easiest to use gd_smouse or gd_kosman to create such a matrix, but in priniciple any other squared distance matrix can be used. see example
eucl.m	A euclidean distance matrix, based on the coordinates of individuals. see example
shuffle	used internally for the permutation calculation
bins	number of bins for the distance classes. Currently only even bins are supported.

Value

Returns a data frame with r values and number of distances within each distance class.
