Did it work;)? I guess the answer is No. First, 'surv' is not a recognized function (I know of).
Second, the ~~ look weird. And, relating a survival object to an event indicator, what relation do you mean it has to 'interval censor data'?

You have to give more detail and be more precise in order to get a valuable answer.
