Sandra,
As far as I am aware, you will have to use a parametric model (survreg) if your
survival times are interval-censored.

Subject: [R] survfit for interval censored data
pHello,/ppI am a new R-user and would like to use survfit for interval
censored data.
Whenever I try I get an error message that states I can only use survfit for
right censored or
counting process data. I was wondering if anyone knows if there is an
additional package available
that can calculate KM curves for interval censored data, or another program
with this
capability?/ppThank you./ppS. Ellis (student)/p
