Эти данные состоят из четырех столбцов: Год, Месяц, День, Осадки.
(1) Я хочу разделить эти данные по классам / категориям осадков:
1-20 mm/day
20-50 mm/day
50-100 mm/day
>100 mm/day
(2) Подсчитайте количество дней, выпадающих на каждую степень выпадения осадков в месяц, и нанесите полученные результаты в виде столбчатой диаграммы с накоплением в R (месяцы по сравнению с количеством).
Что у меня есть на данный момент:
Прямо сейчас я фильтрую значения с помощью пакета dplyr. Вот пример за январь.
library(dplyr)
a<-filter(dat2,Rainfall>=1 &Rainfall <=20)
count(a[which(a$Month==1),])
Я делаю это ежемесячно по четырем категориям. Затем вручную сохраните счетчики.
Я хотел бы спросить, есть ли более эффективный и быстрый способ сделать это. Может быть, простой скрипт с построением графика в конце с помощью ggplot?
Буду признателен за любую помощь в этом вопросе.
