ABSTRACT
This chapter considers delay ordinary differential equations (DODEs) to explain how DODEs can be integrated numerically within the basic R system. It discusses the R routines in detail and presents the solutions numerically and graphically. Generally, the routines include a main program that calls a R library DODE integrator and a subordinate routine that defines the DODE system. The chapter includes examples that present some basic properties of DODEs and the corresponding numerical solutions produced with R utilities. Some of the examples also demonstrate DODE biomedical applications.
