Hi,
I wrote a function that worked well in R, but not in S-Plus, can anyone suggest a solution?
If you change the argument of the function from x to ... it will give Error in eval(expr, envir, enclos) : Object "x" not found which is almost compatible with what it does in S-PLUS.
If you want advice on how to change the behaviour in S-PLUS, this is the wrong list.
f.coxph.zph<-function(x){ cox.fit <- coxph(Surv(time.cox, status.cox) ~ x, na.action = na.exclude, method = "breslow") fit.zph<-cox.zph(cox.fit,transform='log') fit.zph$table[,3] }
