# summary.survexp: Summary function for a survexp object

## Description

Returns a list containing the values of the survival at
specified times.

## Usage

# S3 method for survexp
summary(object, times, scale = 1, ...)

## Value

a list with the following components:

- surv
the estimate of survival at time t.

- time
the timepoints on the curve.

- n.risk
In expected survival each subject from the data set is matched to a
hypothetical person from the parent population, matched on the
characteristics of the parent population.
The number at risk is the number of those hypothetical
subject who are still part of the calculation.

## Arguments

- object
the result of a call to the `survexp`

function

- times
vector of times;
the returned matrix will contain 1 row for each time.
Missing values are not allowed.

- scale
numeric value to rescale the survival time, e.g., if the input data to
`survfit`

were in
days, `scale = 365.25`

would scale the output to years.

- ...
For future methods

## Details

A primary use of this function is to retrieve survival at fixed time
points, which will be properly interpolated by the function.
