[R] problem with the legend when having two plots

[kayj]

I am trying to plot survival curves and here is the code

plot(survfit(Surv(days,status)~group, data=g3),
lty=1:2, mark.time=F,
 ylab="Probability",
 xlab="Suvival Time in Month")
legend(10, 0.2,legend=c("Control","RIT"), lty=c(2,1),
title="Hormonal Therapy", bty="n")

I will get two survival plots with the Control on the top of the RIT


but if I switch to legend=c(“RIT”,”Control”), I will have the same plots but
now the top on is named as RIT and the bottom as Control!

It does not seem that R can tell which graph corresponds to what, am I
missing something.

Thanks for the help
