I have data that has

1) vital status (dead or alive) and 
  2) last day to follow up and 
  3) days to death

in survival analysis in R we have the following formula S1=survfit(Surv(time,status)

my Questions, is time to an event is the days to death?

is the status(censored or not) is the last day to follow up?

and I don't know how to use the vital status here?

I was thinking that vital status can be the status (0=alive,1=death)

but how can I get the time to event from the time to death and last follow up

can anyone correct me if I'm wrong

Thank you
