Exercise

Speeding through the intersection

In the previous lesson, you determined why three countries (South Korea, Brunei, and Iran) don't have matching results in the IMF data compared to the World Bank data for Asia. You'll next see the Asian country entries that do overlap as a nice check.

The datasets from the last lesson (asia_wb, asia_wb_combos, imf_subset, and imf_combos) have been loaded for you. Recall that world_bank_data was trimmed to only focus on Asian countries and a few columns in the asia_wb tibble. A few columns were also selected from imf_data in the imf_subset tibble. asia_wb_combos is distinct combinations of iso and country in asia_wb, and imf_combos is distinct combinations of iso and country for imf_subset.
