How to add specific column to data.set?
Hi I have a data.set with 7 lists, with over 7000 observations in each list. to of the lists contain country names. like: aus dnk fra aus usa aut itl usa . . . etc. My dilemma is that I want to add an extra column/list to my data.set. If the countries are both european it should be assigned 1 or true AND if one or both the countries are non-european it should be assigned 0 or false.
