r - 根据参考日期列R数据框按总和分组

Question

我在 R 中有两个日期列的列表，如下所示：-

d1 <- tibble::tribble(
  ~"Start date",             ~"End date", 
"2010-12-29 00:00:00", "2010-12-31 00:00:00", 
"2011-01-04 00:00:00", "2011-01-04 00:00:00", 
"2011-01-06 00:00:00", "2011-01-12 00:00:00", 
"2011-01-19 00:00:00", "2011-01-21 00:00:00", 
"2011-01-27 00:00:00", "2011-02-04 00:00:00")

我的价格数据框如下：-

预期输出如下：-

Start date            End date                  A   B   C   D   E   F   G   H
2010-12-29 00:00:00 2010-12-31 00:00:00

2011-01-27 00:00:00 2011-02-04 00:00:00     

对于第一个列表中的每个日期范围，我想要这些日期范围的价格数据框中的值的总和。我认为它必须是来自 tidyverse 的 groupby 类型的操作，但我不确定，因为我是 R 新手。请提出前进的方向。

Answer 1

假设df_range和，并在此处df_data使用建议的方法

library(dplyr)
library(fuzzyjoin)
fuzzy_left_join(df_dates, df_data, 
                by = c('Start date' = 'Dates',
                       'End date' = 'Dates'),
                match_fun  = c(`<=`, `>=`)) %>% 
  group_by(`Start date`, `End date`) %>% 
  summarize(across(where(is.numeric), sum)) %>% 
  ungroup()
# # A tibble: 5 x 9
#   `Start date`        `End date`              A     B     C     D     E     F     G
#   <dttm>              <dttm>              <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
# 1 2010-12-29 00:00:00 2010-12-31 00:00:00 239.   96.1  35.1  69.2 127.   68.4  436.
# 2 2011-01-04 00:00:00 2011-01-04 00:00:00  80.0  33.2  12.4  23.6  43.3  23.7  145.
# 3 2011-01-06 00:00:00 2011-01-12 00:00:00 400.  166.   63.7 118.  220.  118.   732.
# 4 2011-01-19 00:00:00 2011-01-21 00:00:00 243.  101.   37.9  71.8 128.   72.1  443.
# 5 2011-01-27 00:00:00 2011-02-04 00:00:00 579.  239.   86.1 170.  299.  173.  1061.

请注意，所有Start date,End date和Dates都应该是 classDate或POSIXct类似的。

可重现的例子

df_dates <- read.table(text = '"Start date"            "End date"
"2010-12-29 00:00:00" "2010-12-31 00:00:00"

"2011-01-19 00:00:00" "2011-01-21 00:00:00"
"2011-01-27 00:00:00" "2011-02-04 00:00:00"',header =  TRUE ) %>% 
  mutate("Start date" = as.POSIXct(Start.date, origin = '1970-01-01'),
         "End date" = as.POSIXct(End.date, origin = '1970-01-01')) %>% 
  select(c("Start date", "End date"))
