Filtering rows

The vote column in the dataset has a number that represents that country's vote:

1 = Yes
2 = Abstain
3 = No
8 = Not present
9 = Not a member

One step of data cleaning is removing observations (rows) that you're not interested in. In this case, you want to remove "Not present" and "Not a member".
