R: Extract a column from an event history object.

getEvent {prodlim} | R Documentation

## Extract a column from an event history object.

### Description

Extract a column from an event history object, as obtained with the function `Hist`.

### Usage

    getEvent(object, mode = "factor", column = "event")

### Arguments

`object` | Object of class `"Hist"`.
`mode` | Return mode. One of `"numeric"`, `"character"`, or `"factor"`.
`column` | Name of the column to extract from the object.

### Details

Since objects of class `"Hist"` are also matrices, all columns are numeric or integer valued. To extract a correctly labeled version, the attribute `states` of the object is used to generate factor levels.

      unclass(x)
      ## extract event (the extra level "unknown" is for censored data)
