Hard to help you here without seeing at least some of your data, or at
least the rows that didn't match. Maybe you've got invalid codes in your
data? How can we tell?

Also, you should say where countryExData comes from, I had to guess it was
from the rworldmap package. That data frame doesn't have the "continent" in
it, so what use is it to you?
