我正在一个项目上，现在我有这个col，它记录一天中不同的时间点。我的数据集中有无数行。 这是我使用独特的功能给您一个想法之后得到的：
unique(cab_rides_filtered$time)
[1] 03:46:40 19:53:20 20:53:20 22:53:20 21:53:20 13:06:40 00:26:40 14:46:40 01:53:20 07:00:00
[11] 10:00:00 13:33:20 18:20:00 06:20:00 14:40:00 17:40:00 20:13:20 14:33:20 08:13:20 01:00:00
[21] 15:20:00 05:46:40 20:06:40 12:06:40 03:13:20 15:53:20 22:13:20 18:40:00 15:40:00 17:33:20
我使用
将列转换为时间格式 chron(times = cab_rides_filtered$time)
我想将一天中的24小时划分为8个日区，并将我现在拥有的所有这些时间点划分为一个称为日区的新列，例如，日区1是从00:00:00到02:59:59。
time day zone
