Kaplan Meier curve

[rawdaberkat]

Hello,
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

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Hello,
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.

57	0	60.0	163	22.69094	6261	0
67	0	70.4	168	24.88403	624	0
