...o at least die gracefully -- but it's not). The simple solution is to not use factors. site1 <- 1*(coxsnps$sitenew==1) site2 <- 1*(coxsnps$sitenew==2) test1 <- coxph(Surv(time, censor) ~ snp1 + sex + site1 + site2 + gene + eth.self + strata(edu), data= coxsnps) output profile1 <- data.frame(snp1=c(0,1), site2=c(0,0), sex=c(0,0), site1=c(0,0), site2=c(0,0), geno=c(0,0) eth.self=c(0,0)) plot(survfit(test1, newdata=profile1)) Note that you do not have to explicitly make "edu" a factor. Since it is included in a strata statement, the coxph r...

I have a situation like below: Samba servers in many cities; one "backup" server in the central location that fetches user profiles each night (changes really with rsync). Users work in many locations; sometimes one user can work in city A, and a day later he can work in city B. This means that they have problems with their profiles - user profile for city A will be different from
