[R] Merge data by coordinates

Dear all, I have two dataframe 1 by latitude and longitude but they always do not match. Is it possible to merge them (e.g. nearest distance)? # Dataframe 1 structure(list(lat = c(54L, 55L, 51L, 54L, 53L, 50L, 47L, 51L, 49L, 54L), lon = c(14L, 8L, 15L, 7L, 6L, 5L, 13L, 5L, 13L, 11L ), PPP2000_40
