[R] Survival Curves

[robgriffin247]

Hi David thanks for the help, i was just looking back to say I have found my
solution (i think) and as you suggested survfit was the way to go.

my solution was this:
model<-survfit(Surv(a$longevity)~a$sex)
plot(model,ylab="proportion alive",xlab="time (days)",col=c("red","blue"))
