The tte_source
object is used to define events and possible censorings.
Arguments
- dataset_name
The name of the source dataset
The name refers to the dataset provided by the

parameter ofderive_param_tte()
.- filter
An unquoted condition for selecting the observations from
dataset
which are events or possible censoring time points.- date
A variable providing the date of the event or censoring. A date, or a datetime can be specified. An unquoted symbol is expected.

A named list returned by
vars()
