Plots the observed (with extrapolation) and expected survival
curves for all strata in an object created by survmean
# S3 method for survmean
lines(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
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.
Other survmean functions: plot.survmean,
