Multidimensional scaling models and methods for the visualization for asymmetric data <doi:10.1111/j.20448317.1996.tb01078.x>. An asymmetric matrix has the same number of rows and columns, and these rows and columns refer to the same set of objects. At least some elements in the uppertriangle are different from the corresponding elements in the lower triangle. An example is a student migration table, where the rows correspond to the countries of origin of the students and the columns to the destination countries. This package provides the slidevector model <doi:10.1007/BF02294474>, a scaling model with unique dimensions and the asymscal model for asymmetric multidimensional scaling. Furthermore, a heat map for skewsymmetric data, and the decomposition of asymmetry are provided for the analysis of asymmetric tables.
