Hi everyone, 

I am doing 5 years mortality predictive index score with survival analysis using a Cox proportional hazard model where I have a continous predictive variable and a right censored response which is the mortality, and the individuals were followed a maximum of 7 years.

I'd like to asses the discrimination ability of survival analysis Cox model by computing a ROC curve and area under the curve for a fixed time (5 years), taking into account that the response is not binary but right censored.

So, is there a function that computes a ROC curve under right censored survival data?

Thank you in advance.
