I don't understand the semantics here. You are mixing cities and countries.

Now you are mixing a single country and a whole continent.
Is this some homework?
You should consider to tell R which cities are in the US and which
countries are in Europe and than try to match appropriately ...
As the footer of this message says:
"PLEASE do read the posting guide
http://www.R-project.org/posting-guide.html"
which tells you to read introductory material and to specify some code
examples and details that you already have got. Then it's much easier
for us to help.
