Summary of a Survival Curve

Description

Returns a list containing the survival curve, confidence limits for the curve, and other information.

Usage

## S3 method for class 'survfit':
summary(object, times, censored=FALSE, scale=1, ...)

Arguments

object output from a call to survfit.
times vector of times; the returned matrix will contain 1 row for each time. This must be in increasing order and missing values are not allowed. If censored=T, the default times vector contains all the unique times in fit, otherwise the default times vector uses only the event (death) times.
censored logical flag: should the censoring times be included in the output? This is ignored if the times argument is present.
scale rescale the survival time, e.g., if the input data to survfit were in days, scale=365.25 would scale the output to years.
... other unused arguments

Value

a list with the following components
