R 定义剪切功能在哪个工作日开始？

我希望Cut（）遵循我在下面定义的dateRange对象，它从星期天开始。 切割功能似乎在周六开始，但我需要它在周日开始

startDate = "2011-07-03"; endDate = "2011-8-07" ## starts on Sunday and ends on Sunday
dateRange <- seq(as.Date(startDate), to = as.Date(endDate), by = "day") ## This step is okay
dateRange
cut(dateRange, "weeks", ordered_result = TRUE) ## This I think where the problem is, it starts on the previous Saturday

startDate=“2011-07-03”；endDate=“2011-8-07”##周日开始，周日结束
dateRange正如Frank所说，cut函数在周一开始，而不是周六。您可以使用start.on.monday选项将其更改为
cut

> weeklyList <- split(dataSet, cut(dateRange, "weeks", ordered_result = TRUE, start.on.monday = FALSE))
> weeklyList

用“周”代替“周”，你能像这样用“7”吗

weeklyList <- split (dataSet, cut(dateRange, 7, ordered_result=T))

weeklyList请通过
cut
功能提供所需的输出。当我使用您的代码时，输出的是与星期一对应的日期。“星期六开始”是什么意思？
cut（dateRange，“weeks”，ordered\u result=TRUE，start.on.monday=FALSE）
？谢谢你，罗兰，很抱歉，你是正确的数据对应于星期一。所需的输出应与dateRange对象相同
weeklyList <- split (dataSet, cut(dateRange, 7, ordered_result=T))
