This function is mainly a simplified interface on the \code{\link[stats]{cmdscale}} function using as much as possible dimensions for the projection. The aims of this PCoA being only to project point in an orthogonal space therefore without any correlation between axis. Because a metric method is used the used distance must be euclidean (cf \code{\link[ProcMod]{is.euclid}}). } \author{ Eric Coissac Christelle Gonindard-Melodelima }
