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 = "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)),
  ...
)

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 means alive (no event) and 1 means dead (event). If type is "interval" then event is ignored.
time2: (character(1))
Name of the column for ending time of the interval for interval censored data, otherwise ignored.
type: (character(1))
The type of censoring. Can be "right" (default), "left" or "interval" censoring.
id: (character(1))
Id for the new task. Defaults to the (deparsed and substituted) name of x.
