Define events and the initial event time

Usage

add_tte(.data = NULL, arm, evts, other_inp = NULL, input)

Arguments

.data: Existing data for initial event times
arm: The intervention for which the events and initial event times are defined
evts: A vector of the names of the events
other_inp: A vector of other input variables that should be saved during the simulation
input: The definition of initial event times for the events listed in the evts argument

Value

A list of initial events and event times

Details

Events need to be separately defined for each intervention.

For each event that is defined in this list, the user needs to add a reaction to the event using the add_reactevt() function which will determine what calculations will happen at an event.

Examples

add_tte(arm="int",evts = c("start","ttot","idfs","os"),
input={
start <- 0
idfs <- draw_tte(1,'lnorm',coef1=2, coef2=0.5)
ttot <- min(draw_tte(1,'lnorm',coef1=1, coef2=4),idfs)
os <- draw_tte(1,'lnorm',coef1=0.8, coef2=0.2)
})
