A graphical user interface (GUI) for performing Multidimensional Scaling applications and interactively analysing the results all within the GUI environment. The MDS-GUI provides means of performing Classical Scaling, Least Squares Scaling, Metric SMACOF, Non-Metric SMACOF, Kruskals Analysis and Sammon Mapping with animated optimisation.
MDSgui is the sole function available to the user from the MDSGUI package. The function calls the MDS-GUI (Multidimensional Scaling Graphical User Interface).
The function requires no parameters when called and data to be analysed is loaded from the MDS-GUI.
The GUI was developed in R with the tcltk package. For the best results it is recommended that R-2.13.0 be used. Also, package version 2_1.1-5 of tcltk2 and 0.0-23 of tkrplot produce the best results.

All MDS is based on the theory covered in "Multidimensional Scaling: Second Edition" by Cox, T.G. and Cox, M.A. (2001) and "Modern Multidimensional Scaling: Theory and Applications Second Edition" by Borg, I. and Groenen, P.J.F. (2005).
Refer to the software User Manual and Vignette for information on the use of the MDS-GUI
