Dear rpact team,
Recently I used the package to do some simple simulation, and I experienced some issue "Error: index error". Below is the minimal code needed to reproduce the error. I looked into the getSimulationSurvival function, and it seems the problem is related to a C function "_rpact_getSimulationSurvivalCpp". Hope you can resolve the issue.
n_subj1 <- 3264
accrual_time1 <- getAccrualTime(
accrualTime = c(0, (20/3), (20/3)*2, (20/3)*3),
accrualIntensity = n_subj1 * c(0.10, 0.35, 0.55)/(20/3)
)
design1 <- getDesignGroupSequential(
typeOfDesign = "asHSD",
gammaA = -8,
informationRates = c(0.6, 1),
beta = 0.1,
alpha = 0.025
)
design_plan1 <- getSampleSizeSurvival(
design1,
pi2 = 0.0781,
hazardRatio = 0.76,
accrualTime = accrual_time1,
eventTime = 12
)
sim1 <- getSimulationSurvival(
design = design1,
pi2 = 0.0781,
directionUpper = FALSE,
hazardRatio = 0.76,
accrualTime = accrual_time1,
eventTime = 12,
plannedEvents = as.numeric(ceiling(design_plan1$eventsPerStage)),
maxNumberOfIterations = 1e2,
longTimeSimulationAllowed = TRUE,
maxNumberOfRawDatasetsPerStage = 1e2
)
