Abstract:
Design Interface ( Di ) is a graphical, interactive tool for spatial design. Its purpose is to facilitate construction and comparison of spatial designs by visualization of the designs themselves and statistics that measure their performance. This package has been implemented as functions within the S programming environment and leverages the wealth of statistical and graphical tools already available in Splus. Di also makes use of object-oriented programming ideas to provide common summary and plot functions for different types of design data sets. User interaction is simplified by the use of menu boxes and other graphical inputs and the package is structured so that new features may be easily incorporated into the program. This manual explains how to use Di gives some examples and also explains how to add new features.
