I want to find out if there is a way of getting an exact y-value based on a x-value for a kaplan-meier curve. I am able to draw the plot, but can't figure out how to get exact values (for example t=1000).
Thanks for your help

my data set is huge, but here's part of it to help illustrate what I would like to do. I would like to find futime (t) = 2000 for example.
Please read the guide again. Look for mention of dput
Also the code that processes your data into the chart should be provided
