i.e. staggered study entry.
This is a helper function of getSimulatedData()
.
Examples
simData <- data.frame(
id = c(1, 1, 2, 3), from = c(0, 1, 0, 0), to = c(1, 2, "cens", 2),
entry = c(0, 3, 0, 0),
exit = c(3, 5.3, 5.6, 7.2), censTime = c(6.8, 6.8, 5.6, 9.4)
)
addStaggeredEntry(simData, 3, accrualParam = "time", accrualValue = 5)
