3 Summary

This week you’ve learned how to take a dataset that contains multiple possible groupings, or subsets of data, and work with those groups to perform a variety of transformations. You’ve explored:

  • ways of grouping data

  • Comtrade data

  • the world of export data

  • how to get data.

Next week looks at how to split the data contained in a dataframe into multiple groups based on the unique ‘key’ values in a single column, or unique combinations of values that appear across two or more columns.
