Performs classical or nonmetric Multidimensional Scaling analysis
Multidimensional Scaling of compositional data
Multidimensional Scaling of distributional data
Multidimensional Scaling of a dissimilarity matrix
Usage
MDS(x, ...)
"MDS"(x, classical = FALSE, ...)
"MDS"(x, classical = FALSE, ...)
"MDS"(x, classical = FALSE, ...)
Arguments
x
an object of class distributional, compositional or diss
...
optional arguments to be passed onto diss (if
x is of class compositional or distributional)
or onto cmdscale or isoMDS (if x is of class
dist).
classical
boolean flag indicating whether classical (TRUE)
or nonmetric (FALSE) MDS should be used
Value
an object of class MDS, i.e. a list containing the
following items:points: a two column vector of the fitted configurationclassical: a boolean flag indicating whether the MDS
configuration was obtained by classical (TRUE) or nonmetric
(FALSE) MDS.diss: the dissimilarity matrix used for the MDS analysisstress: (only if classical=TRUE) the final stress
achieved (in percent)
