= Multidimensional scaling

Construct low-dimensional coordinates representing a <dissimilarity matrix>. Different methods preserve different features: <classical multidimensional scaling> approximates a centered <Gram matrix>, while other methods minimize discrepancies between fitted and supplied distances or preserve distance ordering. The method and dimension determine what geometric claims the resulting display supports.
