Copy the capitals
Sometimes you want to create new columns from your data, and sometimes you want to use an already existing vector. But do you know how to create a new column that only references or only copies the elements of this vector? Let's find out.
You'll be working with the wages dataset, which has been filtered to make things easier. Now it only contains the data for the year 1994. You'll be adding a new column, containing the capitals for each state. Let's try the different methods!
The wages dataset and the DataFrames package have been loaded for you.
