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.
createsitepair(dist, spdata, envInfo, dXCol, dYCol, siteCol, weightsType,
custWeights)
A site-pair table with appropriate distance (dissimilarity) and weight columns used for fitting GDM.
The lower half of a site-by-site distance (dissimilarity) matrix,
provided by the formatsitepair
function.
Input species data, the same as the bioData input to the
formatsitepair
function.
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
.
Input x coordinate, the same as the XColumn input to the
formatsitepair
function.
Input y coordinate, the same as the YColumn input to the
formatsitepair
function.
Site column, taken from either the species or environmental tables.
The method of determining the site-pair weights used in model fitting.
Custom weights, as a vector, if given by the user.
