Cut a dataset for analysis at a specified event count

Takes a time-to-event data set and cuts the data at which an event count is reached.

Usage

cut_data_by_event(x, event)

Arguments

x

A time-to-event dataset, for example, generated by sim_pw_surv().

event

Event count at which data cutoff is to be made.

Value

A data frame ready for survival analysis, including columns time to event (tte), event, the stratum, and the treatment.

Examples

# Use default enrollment and event rates at cut at 100 events
x <- sim_pw_surv(n = 200) |> cut_data_by_event(100)
table(x$event, x$treatment)
#>    
#>     control experimental
#>   0      43           57
#>   1      57           43
