Plot for Survival Tasks

Source: R/autoplot.R
autoplot.TaskSurv.Rd

Generates plots for TaskSurv, depending on argument type:

  • "target": Calls GGally::ggsurv() on a survival::survfit() object. This computes the Kaplan-Meier survival curve for the observations if this task.

  • "duo": Passes data and additional arguments down to GGally::ggduo(). columnsX is target, columnsY is features.

  • "pairs": Passes data and additional arguments down to GGally::ggpairs(). Color is set to target column.

Usage

# S3 method for class 'TaskSurv'
autoplot(
  object,
  type = "target",
  theme = theme_minimal(),
  reverse = FALSE,
  ...
)

Arguments

object

(TaskSurv).

type

(character(1))
Type of the plot. See Description for available choices.

theme

(ggplot2::theme())
The ggplot2::theme_minimal() is applied by default to all plots.

reverse

(logical())
If TRUE and type = 'target', it plots the Kaplan-Meier curve of the censoring distribution. Default is FALSE.

...

(any)
Additional arguments. rhs is passed down to $formula of TaskSurv for stratification for type "target". Other arguments are passed to the respective underlying plot functions.

Value

ggplot2::ggplot() object.
