In Merck/simtrial: Clinical Trial Simulation

Cut a dataset for analysis at a specified event count

Description

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. The class of the data frame is tte_data, and the attribute ratio generated by sim_pw_surv() is also attached.

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)
