Using the Surv() function for GBSG2

In the video, we learned about the Surv() function, which generates a Surv object. Let's look a little deeper into what a Surv object actually is. We will use the GBSG2 data again.

The survival package and GBSG2 data are loaded for you in this exercise.

Instructions

100 XP
  • Create a Surv object with the two variables describing the duration and censoring information of the GBSG2 dataset.
  • Look at the first 10 elements of the object (using indexing with squared brackets []).
  • Look at the summary (summary()) and structure (str()) of the object.
