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.

• Cusp Catastrophe with Sample Trajectories (SAS)

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)
