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 class 'survexp':
summary(object, times, scale = 1, ...)
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
Value
a list with the following components:
survthe estimate of survival at time t.
timethe timepoints on the curve.
n.riskIn 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.
Details
A primary use of this function is to retreive survival at fixed time
points, which will be properly interpolated by the function.
