In PCPS: Principal Coordinates of Phylogenetic Structure

Description

Internal function for organize the results of wcmdscale function. The function computes dissimilarity indices using the function vegdist and perform Principal Coordinates Analysis (PCoA) using the function wcmdscale. If data is of class dist, the funcion do not computes the dissimilarity indices.

Usage

wcmdscale.org(data, method, squareroot, eig, correlations, ...)

Arguments

data	Data matrix or dissimilarities of class dist.
method	Method for dissimilarity index, as accepted by vegdist.
squareroot	Logical argument (TRUE or FALSE) to specify if use square root of dissimilarity index.
eig	Logical argument (TRUE or FALSE) to indicates if eigenvalues are returned.
correlations	Logical argument (TRUE or FALSE) to indicates if correlations between axis and original data are returned.
...	Other arguments passed to wcmdscale function.

Value

values	The eigenvalues, relative eigenvalues and cumulative relative eigenvalues.
vectors	The principal coordinates.
correlations	Correlations between axis and original data.
