spe.mantel.test {NicheBarcoding}

Mantel test between interspecific pairwise genetic distance and ecological distance

Description

Determine the independence between genetic distance and ecological distance for a reference dataset at the level of species.

Usage

spe.mantel.test(
  fas,
  dna.model = "raw",
  ecol.dist.method = "euclidean",
  mantel.method = "spearman",
  permutations = 999,
  en.vir = NULL
)

Arguments

fas

DNAbin, reference dataset containing sample IDs, taxon information, longitude and latitude, and barcode sequences of samples.

dna.model

Character, specifying the evolutionary model to be used; must be one of "raw" (default), "N", "TS", "TV", "JC69", "K80", "F81", "K81", "F84", "BH87", "T92", "TN93", "GG95", "logdet", "paralin", "indel", or "indelblock".

ecol.dist.method

Character, distance measure to be used; must be one of "euclidean" (default), "maximum", "manhattan", "canberra", "binary" or "minkowski".

mantel.method

Character, correlation method, as accepted by cor: "pearson","spearman" (default) or "kendall".

permutations

Numeric, the number of permutations required.

en.vir

RasterBrick, the global bioclimate data output from "raster::getData" function.

Value

The Mantel statistic.

The empirical significance level from permutations.

A matrix of interspecific pairwise genetic distance.

A matrix of interspecific pairwise ecological distance.
