除了星期数，还可以获取日期范围吗？

编程问答 2022-08-12

问题描述

structure(list(ReviewType= c("Primary","Secondary","Primary","Secondary"),Submissiondate= c("2020-09-04","2020-09-03","2020-09-02","2020-09-01","2020-08-31" ),Channel= c("OC","BC","PK" )),class = "data.frame",row.names = c(NA,-5L))

我在下面还有一个查询，我也想对其进行编辑，以使它不告诉我星期数，而是告诉我该周的日期范围：

FinalCounting<-Out %>%
  group_by(Year = year(Submissiondate),Week = week(Submissiondate)) %>% 
  summarise(Primary = sum(ReviewType == "Primary"),Secondary = sum(ReviewType == "Secondary"))

运行查询时，它给出如下输出：

如果不是36，我得到2020-08-31-2020-09-04或什至只是该范围的最后日期，因此我可以将其称为截至报告日期，这可能吗？任何帮助表示赞赏。

解决方法

只需使用Week = paste(lubridate::floor_date(Submissiondate,unit = "weeks"),"-",lubridate::ceiling_date(Submissiondate,unit = "weeks"))创建一列。

您应该能够将此权利放到group_by语句中或之前放到mutate中（以提高可读性）。
