Question

我每小时都有数据。我需要转换成每日，每月，然后在年度。

此外，还缺少一些日期，所以我也希望将其包括在内。

Answer 1

我猜您在谈论在年，月和日中拆分日期变量，然后您想要计算一些您未在示例中包含的另一个varibale的分组统计信息。如果是这种情况，您可以执行以下操作：

# load package 
library(dplyr)

#Date
 Date <- data.frame( Date =strptime(c("24/02/2000/05:25:00", 
"26/02/2000/05:10:00",

"31/03/2000/05:00:00",
"31/03/2000/06:35:00"), format = "%d/%m/%Y/%H:%M:%S"))


# Split your Date variable in days, months, and years

Date[,"Year"] <- format(Date$Date, format = "%Y")
Date[,"Month"] <- format(Date$Date, format = "%m")
Date[,"Day"] <- format(Date$Date, format = "%d")

# Make up some random variable to calculate summary statistics on

Date[,"Random"] <- sample(seq(1,7,1),size=dim(Date)[1], replace = TRUE)

# Now you can calculate grouped statistics by day, month, or year

MonthMean <- Date %>%
                group_by(Month) %>%
                select(Month, Random) %>%
                summarise(Mean = mean(Random))

# Output 
# A tibble: 2 × 2
  Month     Mean

2    03 4.217391

Answer 2

我在日，月和年分割了数据然后计算了Daymean，Monthlymean和Annualmean
