Not sure what that was supposed to do, or even if it will parse.

model<-survfit(Surv(time,status)~1, data=list

Regardless of the error, I am a bit concerned about the order of your
arguments to Surv()
Error in Surv(status, time) : Time and status are different lengths
what does it means (time and status are different lengths?)
Type:
length(list$tatus)
length(list$time)
# And "list" is an exceptionally bad name for an R dataframe.
please do help me..
thank you very much :)
