# Cox proportional hazard lift gain charts

I have built a Cox PH model. I obtained the predicted survival probabilities. My questions are:

1. How to get the predicted survival time, or time to event, using survival probabilities?
2. I need validation using lift charts, as in how many events is the model capturing in the first three deciles.

There are several ways to do this in R. One is to use the survest function in the rms package in conjunction with that package's cph function.
