Как рассчитать интерполированные значения для отсутствующих точекна основе соседних ячеек.Интерполированные значения должны рассчитываться как длинные и только в том случае, если по крайней мере две записанные точки находятся рядом.способ, как сказать R, когда интерполировать, а когда нет.
Пример данных:
egg_data <- structure(list(Latitude = c(54.25, 54.25, 54.25, 54.25, 54.25,
