createsitepair: Create Site-Pair Table

In gdm: Generalized Dissimilarity Modeling

Create Site-Pair Table

Description

Creates a site-pair table from the lower half of a site-by-site distance (dissimilarity) matrix. This function is called from the formatsitepair function and not needed by the user.

Usage

createsitepair(dist, spdata, envInfo, dXCol, dYCol, siteCol, weightsType,
custWeights)

Arguments

dist	The lower half of a site-by-site distance (dissimilarity) matrix, provided by the formatsitepair function.
spdata	Input species data, the same as the bioData input to the formatsitepair function.
envInfo	Input environmental data. Only accepts data tables as input. If the environmental data for formatsitepair are rasters, the data would have been extracted into table format within formatsitepair.
dXCol	Input x coordinate, the same as the XColumn input to the formatsitepair function.
dYCol	Input y coordinate, the same as the YColumn input to the formatsitepair function.
siteCol	Site column, taken from either the species or environmental tables.
weightsType	The method of determining the site-pair weights used in model fitting.
custWeights	Custom weights, as a vector, if given by the user.

Value

A site-pair table with appropriate distance (dissimilarity) and weight columns used for fitting GDM.

Note

This function is called from the formatsitepair function and not needed by the user.
