A common key to look up values, like iso in the imf_data and world_bank_data tibbles, is important in joining datasets. But wouldn't country also work? You'll examine this in this lesson.

Throughout this chapter, the dplyr package has been loaded for you.

world_bank_data has been 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 and imf_subset have been loaded for you.

Perform the appropriate joins to obtain the following results. Let dplyr identify the keys to join here.

  • 3
