- We rewrite the metric/nonmetric and weighted/unweighted versions of the smacof program for square symmetric data as one monolithic C program. R is used for taking care of the data and parameter setup, the I/O, and of issuing a single call to .C() to start the computations. This makes this new smacofSS() program five to fifty times as fast (for our examples) as the smacofSym() function from the R smacof package. Utilities for various initial configurations and plots are included in the package. Examples are included to compare output and time for the R and C versions and to illustrate the various plots.
