Built-in functions : parent function

parent function

parent(1)

Returns the id (instance number) of the individual whose reproduction gave rise to this one, or 0 if the individual being considered was created at the start of the simulation or by immigration.

Input: numeric (but a dummy value: use the value 1).

Result: integer (in fact, a negative integer number, being the instance number of a member of a population submodel. These are all numbered from -1 downwards.)

Comment:

This function is vital for the simulation of any form of biological inheritance from one generation to the next. You have to know who the parent is before you can allow the newly-created individual to inherit (possibly with modification) one or more of the characteristics of the parent.
