In mlr3proba: Probabilistic Supervised Learning for 'mlr3'

Convert to a Survival Task

Description

Convert object to a survival task (TaskSurv).

Usage

as_task_surv(x, ...)

## S3 method for class 'TaskSurv'
as_task_surv(x, clone = FALSE, ...)

## S3 method for class 'data.frame'
as_task_surv(
  x,
  time = "time",
  event = "event",
  time2,
  type = "right",
  id = deparse(substitute(x)),
  ...
)

## S3 method for class 'DataBackend'
as_task_surv(
  x,
  time = "time",
  event = "event",
  time2,
  type = "right",
  id = deparse(substitute(x)),
  ...
)

## S3 method for class 'formula'
as_task_surv(x, data, id = deparse(substitute(data)), ...)

Arguments

x	(any) Object to convert, e.g. a data.frame().
...	(any) Additional arguments.
clone	(logical(1)) If TRUE, ensures that the returned object is not the same as the input x.
time	(character(1)) Name of the column for event time if data is right censored, otherwise starting time if interval censored.
event	(character(1)) Name of the column giving the event indicator. If data is right censored then "0"/FALSE means alive (no event), "1"/TRUE means dead (event). If type is "interval" then "0" means right censored, "1" means dead (event), "2" means left censored, and "3" means interval censored. If type is "interval2" then event is ignored.
time2	(character(1)) Name of the column for ending time for interval censored data, otherwise ignored.
type	(character(1)) Name of the column giving the type of censoring. Default is 'right' censoring.
id	(character(1)) Id for the new task. Defaults to the (deparsed and substituted) name of x.
data	(data.frame()) Data frame containing all columns referenced in formula x.
