According to the guidelines (if I'm not mistaken), the code below is sufficient (without any specification) to give Kaplan-Meier curves with censored data markings on Kaplan-Meier curves. But in my case censored data don't appears on the curves?!
library(survival) mydata<-read.csv (file="C:/mydata/mydata.csv", header=TRUE, sep=";" ) # Sic! The separator in my csv file is ";" dput (mydata, "dputmydata.r") #attached Y <- Surv (mydata$time, mydata$status == 2) # 2 -- encodes event km <- survfit (Y~mydata$stage) plot (km) ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
