quantile.survfitr: Quantiles of the survival time

In survrec: Survival Analysis for Recurrent Event Data

Quantiles of the survival time

Description

Returns, for each requested probability p, the first time at which the estimated survival function falls to 1 - p or below (so probs = 0.5 is the median survival time). NA is returned when the curve does not reach the requested level.

Usage

## S3 method for class 'survfitr'
quantile(x, probs = c(0.25, 0.5, 0.75), ...)

Arguments

x	a survfitr object.
probs	vector of probabilities.
...	ignored; kept for compatibility with the generic.

Value

A named vector of survival times, or a matrix with one row per group when the fit has strata.

  data = MMC,
  type = "wang-chang"
)
