Summarize simulations to get operating characteristics
summarise_sims(data)list (of data frames) or a single data frame. If summarizing a
single run of simulations, data will be a data.frame object
returned from survival_adapt. If summarizing multiple
simulation scenarios, data will be a list object, with each
element being a data.frame object.
Data frame reporting the operating characteristics, including the type 2 error (which will be equal to the type I error in the null case); the proportion of trials that stopped for early expected success, futility, or went to the maximum sample size. The average stopping sample size (and standard deviation) are also recorded. The proportion of trials that stopped early for expected success, yet went to ultimately fail are also reported.
