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?
?survfit
?survfit.formula

Thank you so much in advance.

Dear David,
Thank you for your reply. I realized that the summary function can
help me in finding the the order of the curves.
The 0.95UCL (95% upper confidence level) column in particular seems
to follow the same pattern as the curves on the plot.
That would not have been my prediction. The 95% UCL could be high
simply because the sample size in that group was small.

I am new to survival analysis, so please correct me if I am wrong.
Thanks,

Dear List,
I used survival package of R and was able to generate KM plots. Now
I need
help in finding the top curve in a non-visualization way. I mean to
say that
I would like to know the order of curves through any existing
methods rather
than looking at the KM plots. I need this information as I am
generating KM
plots for thousands of genes.
Why aren't you taking the KM estimate at a particular time?

I would really appreciate if some one can direct me and help me.
Thanks,
