Description Usage Arguments Value Author(s) See Also Examples

event_source objects are used to define events as input for the derive_param_tte() function.

1	event_source(dataset_name, filter = NULL, date, set_values_to = NULL)

`dataset_name`	The name of the source dataset The name refers to the dataset provided by the `source_datasets` parameter of `derive_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, a datetime, or a character variable containing ISO 8601 dates can be specified. An unquoted symbol is expected.
`set_values_to`	A named list returned by `vars()` defining the variables to be set for the event or censoring, e.g. `vars(EVENTDESC = "DEATH", SRCDOM = "ADSL", SRCVAR = "DTHDT")`. The values must be a symbol, a character string, a numeric value, or `NA`.

An object of class event_source, inheriting from class tte_source
