State {ABM}

The state of an agent

Description

In this framework, a state is a list, each named component is called a domain. The value of a domain can be any R value. The list can be at most one unnamed value, which corresponds to a domain with no name. This is useful if there is only one domain.

Details

A state can be matched to an R list (called a rule in this case). The state matches the rule if and only if each domain (names of the list) in rule has the same value as in state. The domains in domains of the state not listed in rule are not matched. In addition, to match to a rule, the domain values must be either a number or a character. This is useful for identifying state changes. See newCounter() and the Simulation class' addTransition method for more details.
