I made a survival analysis using survreg function. Its OK. But, I need to show 
in the graph 1-weibull curves.

Ploting weibull curve a add the estimated points following these steps:

fit <- survfit(Surv(Time,Censor)~Group)


I have 3 groups.

But I dont know how to plot the correct points on a inverse weilbull graph. I 
try to use points(1-fit[1]) but dont work. I try others way to make this, but 
all dont make sense.

Anybody can help me?
