Use cases of gs_power_ahr()

Example 1

x <- gs_power_ahr(enrollRates = tibble(Stratum = "All", duration = c(2, 2, 10), rate = c(3, 6, 9)),
                  failRates = tibble(Stratum = "All", duration = c(3, 100), failRate = log(2) / c(9, 18), 
                                     hr = c(.9, .6), dropoutRate = rep(.001, 2)),
                  analysisTimes = c(12, 24, 36), events = NULL,
                  binding = TRUE,
                  upper = gs_spending_bound,
                  upar = list(sf = gsDesign::sfLDOF, total_spend = 0.025, param = NULL, timing = NULL),
                  lower = gs_spending_bound,
                  lpar = list(sf = gsDesign::sfLDOF, total_spend = 0.025, param = NULL, timing = NULL))
