[R] [R-pkgs] smacof package for multidimensional scaling
Dear UserR's, The smacof package (see also our PsychoR repository on http://r-forge.r-project.org/projects/psychor/) is uploaded on CRAN. This package provides the following approaches of multidimensional scaling (MDS) based on stress minimization by means of majorization (smacof): - Simple smacof on symmetric dissimilarity matrices - smacof for rectangular matrices (unfolding models) - smacof with constraints on the configuration (linear, unique, diagonal, or user-specified constraints; fitting simplex or circumplex) - 3-way smacof for individual differences (including constraints for idioscal, indscal, and identity) - Sphere projections (spherical smacof, primal and dual algorithm). Each of these approaches is implemented in a metric and nonmetric manner including primary, secondary, and tertiary approaches for tie handling. Various 2- and 3D-plots are provided and a package vignette is included.
