lines.survmean: Graphically Inspect Curves Used in Mean Survival Computation

In popEpi: Functions for Epidemiological Analysis using Population Data

Graphically Inspect Curves Used in Mean Survival Computation

Description

Plots the observed (with extrapolation) and expected survival curves for all strata in an object created by ⁠[survmean]⁠

Usage

## S3 method for class 'survmean'
lines(x, ...)

Arguments

x	a survmean object
...	arguments passed (ultimately) to matlines; you may, therefore, supply e.g. lwd through this, though arguments such as lty and col will not work

Details

This function is intended to be a workhorse for ⁠[plot.survmean]⁠. If you want finer control over the plotted curves, extract the curves from the survmean output using

attr(x, "curves")

where x is a survmean object.

Value

Always returns NULL invisibly. This function is called for its side effects.
