[R] How to add specific column to data.set?

[phillip03]

So the lapply function checks every country pair row for row (in my country1
and country2 column) and send back a true if both countries are EU?

How do I get a 1 instead of true and 2 instead of false?

You have been a BIG help.

I have a WHOLE assignment to get done, so maybe I'll post some more
questions :)
