lifetable.matrix: Life table

Description

Create simple life table

Usage

## S3 method for class 'matrix':
lifetable(x, strata = list(), breaks = c(),
   confint = FALSE, ...)
 ## S3 method for class 'formula':
lifetable(x, data=parent.frame(), breaks = c(),
   confint = FALSE, ...)

Arguments

x

time formula (Surv) or matrix/data.frame with columns time,status or entry,exit,status

strata

Strata

data

data.frame

breaks

Time intervals

confint

If TRUE 95% confidence limits are calculated

...

Additional arguments to lower level functions

Examples

library(timereg)
data(TRACE)
lifetable(Surv(time,status==9)~sex+I(cut(wmi,c(-Inf,1,1.5,Inf))),
              data=TRACE,breaks=c(0.2),confint=TRUE)

d <- with(TRACE,lifetable(Surv(time,status==9)~sex+vf,breaks=c(0,0.2,0.5,8.5)))
summary(glm(events ~ offset(log(atrisk))+factor(int.end)*vf + sex*vf,
            data=d,poisson))
