In vandy10s/extractKM: Functions that Extract Data from the Kaplan Meier (KM) Curve

extractKM

The algorithm by Guyot et al.(2012) derives data from KM curve that are close to the original individual patient time-to-event data (IPD). The functions in this package map from digitised curves back to KM data using the algorithm in an easier and more convenient way. There are 3 functions which require different information types or conditions. To install the package using R, please run the commands below.

library(remotes)
remotes::install_github("vandy10s/extractKM")

2. km.event

km.event function derives or extracts IPD when only total number of events information are available. To check the exmaple, run the following command.

example(km.event)

3. km.tab.event
