我想取列aantal_vangtuigeenheden和totaalgewicht_vangst的和，我使用了以下代码：
Data_traject <- Data_trajectgegevens_ruw
Data_traject$datum <- as.Date(Data_traject$datum, format="%Y-%m-%d")
#Data_traject$tijd <- format(as.POSIXct(strptime(Data_traject$tijd,"%Y-%m-%d %H:%M:%S",tz="")) ,format = "%H:%M:%S")
Data_traject$jaar <- as.character(Data_traject$jaar)
Data_traject$projectnr <- as.character(Data_traject$projectnr)
Data_traject$waterdiepte_m <- as.numeric(Data_traject$waterdiepte_m)
Data_traject$`aantal nachten` <- round(Data_traject$`aantal nachten`, digits = 0)
Data_traject$totaalgewicht_vangst <- as.numeric(Data_traject$totaalgewicht_vangst)
Data_traject$`datum opgehaald` <- as.Date(Data_traject$`datum opgehaald`, format="%Y-%m-%d")
library(lubridate)
library(tidyverse)
cpue_monitoring <- cpue_monitoring %>%
mutate(Datum = format(date(`datum opgehaald`), "%Y-%m-%d")) %>%
group_by(locatie, deelgebied, `datum opgehaald`) %>%
summarise_at(c("aantal_vangtuigeenheden", "totaalgewicht_vangst"), sum)
似乎大多数值都是正确计算的，接受列aantal_vangtuigeenheden中的36值。它们需要是48的总和。这意味着R在进行计算时对一些行进行了scipped。我检查了我的excel文件和Rfiles，但一切似乎都很好。在这种情况下，我如何找到问题？

为什么你期望到处都有48个，只是检查你的样本数据并挑选一组。我们很快就看到，该分组只有3条记录，那么为什么你期望aantal_vangtuigeenheiden的总和超过36呢？
cpue_monitoring %>% filter(locatie == "Berkenwoude" & deelgebied == "Pilotgebied" & `datum opgehaald` == as.Date("2021-08-17"))
# A tibble: 3 x 7
jaar locatie bemonstering deelgebied aantal_vangtuigeenheden `datum opgehaald` totaalgewicht_vangst
<chr> <chr> <chr> <chr> <dbl> <date> <dbl>
1 2021 Berkenwoude Monitoring Pilotgebied 12 2021-08-17 1
2 2021 Berkenwoude Monitoring Pilotgebied 12 2021-08-17 0.08
3 2021 Berkenwoude Monitoring Pilotgebied 12 2021-08-17 0.58
因此，如果您的文件最初有更多的行，那么您的问题就出现在前一步，例如在将数据读取到R.中时
正如@Merijn van Tilborg也提到的，36似乎是以正确的方式计算的。您可以使用以下代码：
library(tidyverse)
library(lubridate)
cpue_monitoring <- cpue_monitoring %>%
mutate(Datum = format(date(cpue_monitoring$`datum opgehaald`), "%Y-%m-%d")) %>%
group_by(locatie, deelgebied, Datum) %>%
summarise(across(where(is.numeric), sum))
输出：
`summarise()` has grouped output by 'locatie', 'deelgebied'. You can override using the `.groups` argument.
# A tibble: 44 × 5
# Groups: locatie, deelgebied [5]
