First of all, please replace your = with - per general R-usage rules.
Next: you need to provide a clear listing of doAirport.R so we can tell
what it actually is, and what you've done outside the function.
That said, my suspicion is that your parent function (the one which
calls doAirport)

The function is doing exactly what you are telling it to do. You have
