tte_source: Create a 'tte_source' Object

In admiral: ADaM in R Asset Library

Create a tte_source Object

Description

The tte_source object is used to define events and possible censorings.

Usage

tte_source(
  dataset_name,
  filter = NULL,
  date,
  censor = 0,
  set_values_to = NULL,
  order = order
)

Arguments

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 or expression providing the date of the event or censoring. A date, or a datetime can be specified. An unquoted symbol or expression is expected. Refer to derive_vars_dt() or convert_dtc_to_dt() to impute and derive a date from a date character vector to a date object.
censor	Censoring value CDISC strongly recommends using 0 for events and positive integers for censoring.
set_values_to	A named list returned by exprs() defining the variables to be set for the event or censoring, e.g. exprs(EVENTDESC = "DEATH", SRCDOM = "ADSL", SRCVAR = "DTHDT"). The values must be a symbol, a character string, a numeric value, an expression, or NA.
order	Sort order An optional named list returned by exprs() defining additional variables that the source dataset is sorted on after date.

Value

An object of class tte_source
