The UnempDur dataset

The UnempDur dataset contains information on how long people stay unemployed. In this case, the event (finding a job) is something positive. This information is stored in the censor1 variable, which has a value of 1 if an individual was re-employed at a full-time job. The spell variable indicates the length of time an individual was unemployed in number of two-week intervals.

In this exercise, you'll explore these censored values and create a Surv object, just as you did in the previous exercises with the GBSG2 dataset.

Load the UnempDur dataset from the Ecdat package.
Count the number of censored and uncensored observations.
Create a barplot of the number of censored and uncensored observations.
Create a Surv object using censor1 and the variable describing duration.
