In lrstat: Power and Sample Size Calculation for Non-Proportional Hazards and Beyond

Accrual Duration to Enroll Target Number of Subjects

Description

Obtains the accrual duration to enroll the target number of subjects.

Usage

getAccrualDurationFromN(
  nsubjects = NA_real_,
  accrualTime = 0L,
  accrualIntensity = NA_real_
)

Arguments

nsubjects	The vector of target number of subjects.
accrualTime	A vector that specifies the starting time of piecewise Poisson enrollment time intervals. Must start with 0, e.g., c(0, 3) breaks the time axis into 2 accrual intervals: [0, 3) and [3, Inf).
accrualIntensity	A vector of accrual intensities. One for each accrual time interval.

Value

A vector of accrual durations.

Examples

getAccrualDurationFromN(nsubjects = c(20, 150), accrualTime = c(0, 3),
                        accrualIntensity = c(10, 20))
