as_task_surv {mlr3proba} | R Documentation

## 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)),
      ...
    )

### 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`.
