hallo terry:
I attached araceae data set,
when I use this:
surara<-survfit(Surv(time,time2,event)~categoria)
Call: survfit(formula = Surv(time, time2, event) ~ categoria)
records n.max n.start events median 0.95LCL 0.95UCL

Asunto: Re: survival analysis: interval censored data
You have still not given me enough information to reproduce your
problem. "Why doesn't it include all years?" I have no way of knowing,
since we have no data.

halo david
when I use type= 'interval'
Call: survfit(formula = Surv(ingreso, fecha, estado, type = "interval")
~
categoria)
and when I use just
Call: survfit(formula = Surv(ingreso, fecha, estado) ~ categoria)
I don t know why when I use type = "interval" it does not survival
calculed for very year
