autoplot.survival function

Plot survival curves

Quickly plot survival curves stored in a survival object.

## S3 method for class '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.

Returns

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.
