R: Plot a 'Surv' object.

plotSurv {survMisc} | R Documentation

## Plot a `Surv` object.

### Description

Plot a `Surv` object.

### Usage

    ## S3 method for class 'Surv'
    plot(x, l = 3, ...)

### Arguments

`x` | A `Surv` object
`l` | length of arrow. Length is `l / nrow(x)`
`...` | Additional arguments. These are passed to as `...` (an ellipsis) to the following functions, respectively: `graphics::arrows` for plotting right- or left-censored observations `graphics::segments` for plotting interval-censored observations

### Value

A graph (base graphics). The type of graph depends on the `type` of the `Surv` object. This is given by `attr(s, which="type")` :

`counting` | Lines with an arrow pointing right if right censored.
`right` | Lines with an arrow pointing right if right censored.
`left` | Lines with an arrow pointing left if left censored.
`interval` | If censored: arrow points right right censored arrow points left left censored If not censored: lines observations of more than one time point points observation of one time only (i.e. start and end times are the same)

### Examples

    df0 <- data.frame(t1=c(0, 2, 4, 6, NA, NA, 12, 14),
                      t2=c(NA, NA, 4, 6, 8, 10, 16, 18))
    s5 <- Surv(df0$t1, df0$t2, type="interval2")
    plot(s5)
