How to read the data `veteran` from package `survival` in r?

[Jesmin]

`state.x77` is a `R` built-in data set.To read the data `state.x77` , i only write `state.x77` in the `R console` and the data set comes immediately.

Now i have to read the data `veteran` from package `survival`. But if i write

 veteran
 Error:object veteran not found.

How can i read the data `veteran` from package `survival`?

Some packages have lazy loading of data automatically when the package is called and the data sets for that package are already loaded and ready. For others you have to explicitly call the data set using data as seen here:

data(veteran, package = "survival")
veteran
