plot.survfitr: Plot survival curves of recurrent event data

In survrec: Survival Analysis for Recurrent Event Data

Plot survival curves of recurrent event data

Description

Plots the estimated survival (or probability) function from a survfitr object, one curve per group when the fit has strata. Additional fits can be added to the same axes with the lines method.

Usage

## S3 method for class 'survfitr'
plot(x, conf.int = TRUE, prob = FALSE, ...)

## S3 method for class 'survfitr'
lines(x, prob = FALSE, ...)

Arguments

x	an object of class survfitr (output of survfitr(), psh_fit(), wc_fit() or mlefrailty_fit()).
conf.int	if TRUE (default), pointwise 95\ are drawn for the estimators that provide standard errors.
prob	if TRUE the probability function (1 - survival) is drawn instead of the survival function.
...	additional arguments passed to plot().

Value

No return value; called for its side effect.

fit <- survfitr(Survr(id, time, event) ~ group,

  type = "wang-chang"
)
