Life table

Create simple life table

# S3 method for class 'matrix'
lifetable(x, strata = list(), breaks = c(),
   weights=NULL, confint = FALSE, ...)

 # S3 method for class 'formula'
lifetable(x, data=parent.frame(), breaks = c(),
   weights=NULL, confint = FALSE, ...)

Arguments

x

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

strata

strata

breaks

time intervals

weights

weights variable

confint

if TRUE 95% confidence limits are calculated

...

additional arguments to lower level functions

data

data.frame
