<p>Hello,</p><p>I 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?</p><p>Thank you.</p><p>S.
