smacof package for 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 approache...

Creating covariance matrices for simple and complex factor structure
Hello all,
I'm trying to create covariance matrices that, when processed via CFA methods (in the sem package) will produce exact fit with simple structure down to poor fit with cross loadings. What is the best way to do this? I don't really need to have the exact loop code, but maybe an explanation of how to make a few of the matrices or an explanation of the rationale behind performing
