Define a Markov Model State

Source: R/states_define.R

Define the values characterising a Markov Model state for 1 cycle.

define_state(..., starting_values = define_starting_values())

define_state_(x)

# S3 method for state
modify(.OBJECT, ...)

Arguments

...

Name-value pairs of expressions defining state values.
starting_values

Optional starting values defined with define_starting_values().
x

Used to work around non-standard evaluation.
.OBJECT

An object of class state.

Value

An object of class state (actually a named list of lazy expressions).

Details

As with define_parameters(), state values are defined sequentially. Later state definition can thus only refer to values defined earlier.

For the modify function, existing values are modified, no new values can be added. Values order matters since only values defined earlier can be referenced in later expressions.

Examples

st <- define_state(
  cost = 6453,
  utility = .876
)
st

#> A state with 2 values.
#> 
#> cost = 6453
#> utility = 0.876
