varying accrual intensity in getSimulationCounts · Issue #84 · rpact-com/rpact · GitHub

I'm trying to use projected enrollment counts for simulating a trial with count endpoint by specifying a piecewise acrualIntensity and accrualTime. This works well with getSimulationSurvival. However for counts I get the error below. I am using rpact 4.2.0.

I briefly looked in the code to see if I was specifying something wrong and noticed a possible divide by 0 case which would occur if intensity drops to 0 at some time.

rpact::getSimulationCounts(
    theta = 1.8,
    lambda2 = 0.2,
    followUpTime = 24,
    maxNumberOfIterations = 10,
    accrualTime = c(0, 1, 2),
    accrualIntensity = c(5, 15),
    overdispersion = 2
    )

Error in seq.default(0, accrualTime, length.out = n1) : 
  'to' must be of length 1

rpact::getSimulationCounts(
    theta = 1.8,
    lambda2 = 0.2,
    followUpTime = 24,
    maxNumberOfIterations = 10,
    accrualTime = c(0, 1, 2, 3),
    accrualIntensity = c(5, 0, 15),
    overdispersion = 2
)

Error in seq.default(accrualTime[i - 1] + 1/accrualIntensity[i], accrualTime[i],  : 
  'from' must be a finite number
