Visualizing a Cox model

In this exercise we will reproduce the example from the video following the steps:

Compute Cox model
Decide on "imaginary patients"
Compute survival curves
Create data.frame with survival curve information
Plot

We will focus now on the last two steps in this exercise.

The survival and survminer packages and the GBSG2 data are loaded for you in this exercise. The Cox model cxmod, the imaginary patient data newdat, and the survival curve information cxsf from the previous exercise are also available.
