Exercise

Further investigations

You saw in the previous exercise that some countries in the World Bank data (South Korea, Brunei, and Iran) don't have matching results in the IMF data. Let's focus on their iso codes using the distinct() function to investigate further.

The iso codes for South Korea, Brunei, and Iran are stored for you in the suspect_isos vector. asia_wb and imf_subset have been loaded for you too.
