getOneToTwoRows: Transitions from the Intermediate State to the Absorbing State

Description

This function creates transition entry and exit times from the intermediate state to the absorbing state for an existing data frame containing the exit times out of the initial state.

Usage

getOneToTwoRows(simDataOne, transition)

Value

This returns a data frame with one row per patient for the second transition, i.e. the transition out of the intermediate state. This is a helper function of getSimulatedData().

Arguments

simDataOne

(data.frame)
a data frame containing all patients with transitions into the intermediate state. See getSimulatedData() for details.

transition

(TransitionParameters)
transition parameters comprising hazards, corresponding intervals and weibull_rates, see exponential_transition(), piecewise_exponential() and weibull_transition() for details.

Examples

simDataOne <- data.frame(
  id = c(1:3), to = c(1, 1, 1), from = c(0, 0, 0), entry = c(0, 0, 0),
  exit = c(3, 5.6, 7.2), censTime = c(6.8, 5.9, 9.4)
)
transition <- exponential_transition(1, 1.6, 0.3)
getOneToTwoRows(simDataOne, transition)
