Graphics Programs

1. A program written in R and SAS for producing graphical output and analyses of nonlinear differential equation systems, including chaos models.

- The Lorenz 3D chaos model (using the R Programming Language)
- The Lorenz 3D chaos model (SAS, used in Chaos and Catastrophe Theories)

2. A program written in SAS for producing a graph of a cusp catastrophe with sample trajectories.

3. A program written in Think Pascal for graphical and numerical analysis of highly nonlinear and potentially chaotic mathematical models of social phenomena.

- Chaos1 (written in Think Pascal, Macintosh; used in
*Serpents in the Sand*)

4. A program for graphical and numerical analysis of highly nonlinear catastrophe theory mathematical models.

- Catastrophe1 (written in Think Pascal, Macintosh; used in
*Serpents in the Sand*)
