Exercise: Life expectancy in Austria

The gapminder_austria dataset contains information about the economic and demographic change in Austria over the last decades. To inspect how the life expectancy in Austria changed over time, create a subset of the tibble that contains only the necessary columns for this task:

  1. Use the dplyr select() function and define gapminder_austria as the input tibble.
  2. Keep only the columns year and lifeExp in the output dataset.

Note that the dplyr package is already loaded.
