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.
