Ok David, Thanks for clearing my misconception. Then could you please suggest me how I could get the KM estimate for a time point. I remember reading the formula for calculating the KM. Do, I have to write a method to compute the KM estimate or will the survival package provide it for me?
Thank you so much in advance.
