Quickly plot survival curves stored in a `survival`

object.

# S3 method for survival
autoplot(
object,
labels = NULL,
ci = FALSE,
prob = 0.95,
ci_style = c("ribbon", "line"),
geom_alpha = 0.3,
...
)

## Arguments

object |
A `survival` object. |

labels |
A list of named vectors containing the values and labels of
variables. The elements of each vector are the values of a variable and the
names are the labels. The names of the list are the names of the variables.
See the output returned by `get_labels()` for an example. |

ci |
A logical value indicating whether confidence intervals should be
plotted. Default is `FALSE` . |

prob |
A numeric scalar in the interval `(0,1)` giving the confidence interval.
Default is 0.95 for a 95 percent interval. |

ci_style |
Style to use for the confidence interval if `ci = TRUE` . If
`"line"` , then dashed lines are used; if `"ribbon"` , then shaded confidence
bands are plotted using `ggplot2::geom_ribbon()` . |

geom_alpha |
The opacity for the shaded confidence bands when
`ci_style = "ribbon"` . This is the value of the value of the `alpha` aesthetic
passed to `ggplot2::geom_ribbon()` . |

... |
Further arguments passed to and from methods. Currently unused. |

## Value

A `ggplot`

object.

## Note

If there are multiple patients, then survival probabilities are
averaged across patients (using the weights in `patient_wt`

if available)
prior to plotting.
