A great selection

The imf_data tibble contains characteristics of countries including (but not limited to) currency conversion rate compared to a US dollar, gross domestic product (in billions of US dollars), and population across many years. In this exercise, you'll explore this data from the International Monetary Fund (IMF) further.

Throughout this chapter, dplyr and imf_data have been loaded for you. A string vector including a few countries is also available as countries_vector for this exercise.
