survmean
"plot"(x, ...)survmean objectmatlines; you
may, therefore, supply e.g. xlab through this, though arguments
such as lty and col will not worksurvmean. This function is intended only
for graphically inspecting that the observed survival curves with extrapolation
and the expected survival curves have been sensibly computed in 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.
