%description
Implements the following approaches for multidimensional scaling (MDS)
based on stress minimization using majorization (smacof):
ratio/interval/ordinal/spline MDS on symmetric dissimilarity matrices, MDS
with external constraints on the configuration, individual differences
scaling (idioscal, indscal), MDS with spherical restrictions, and
ratio/interval/ordinal/spline unfolding (circular restrictions,
row-conditional). Various tools and extensions like jackknife MDS,
bootstrap MDS, permutation tests, MDS biplots, gravity models,
unidimensional scaling, drift vectors (asymmetric MDS), classical scaling,
and Procrustes are implemented as well.
