r - 如何在r中分割一天中的不同时间

Question

我正在做一个项目，现在我有这个记录一天中不同时间点的 col。我的数据集中有无数行。这是我在使用独特的功能给你一个想法后得到的：

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

我通过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 小时分割成 8 个天区，并将我现在拥有的所有这些时间点分割成一个名为日区的新列，例如，日区 1 是从 00:00:00 到 02:59 :59。

time                   day zone
03:46:40                  2

dput(unique(cab_rides_filtered$time))
