Hi, I am working on transforming a SAS code to R code. It's about the survival analysis and the SAS code is as below: -------------------------------------- proc lifetest data=surdata plot=(s); time surv*censht(1); strata educ; title 'Day 1 homework'; run; ----------------------------------------
here is the data: subject surv censht educ 1 78 1 1 2 70 1 0 3 60 0 1 4 50 1 1 5 90 0 1 . . . . . . . . . . . . 100 50 1 0 -------------------------------- In the dataset, 'subject' is suject ID, 'surv' is the survival time, 'censht' is the indicator of censor, 'educ' is the strata variable indicating the education status. How convert such SAS codes to R code? thank you very much, karena -- View this message in context: http://r.789695.n4.nabble.com/Convert-SAS-code-to-R-code-about-survival-analysis-tp3594657p3594657.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [email protected] mailing list 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.
