r = business n = economy and in first *uhm thinking* forgot about that ... iam getting old

I purchased an economy M class fare: JFK-FRA-JFK. At check-in I received an upgrade (apparently oversold in econ) to business class (FRA-JFK) and R class was printed on my boarding pass. So far as I can gather, I'm entitled to economy (M-class) miles. Should I get the miles? Or does the upgrade cancel them out?
