define_state: Define a Markov Model State

In heemod: Markov Models for Health Economic Evaluations

Define a Markov Model State

Description

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

Usage

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

define_state_(x)

## S3 method for class '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.

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.

Value

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

Examples

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