Hi Steven, As near as I can tell, no precision is lost. R is just being courteous and not excessively filling our consoles. Try:
print(airports[1,"latitude_deg"], digits = 22) which is the most digits R will print (although internally it can store more I believe). Alternately, you can convert it to character class: as.character(airports[1, ]) So in short, this is just a cosmetic feature of presenting the data, not its actual storage.
