按時間排序矢量

Question

我有一個由時間組成的因子變量。當我試圖把它變成一個因素時，R按從低到高的順序排列它們。 Unforunately，這意味着我最終像下面這樣：

1:48:55 1:53:11 1:58:18 10:04:01 10:12:45 10:14:16 
10:20:24 10:21:59 10:23:11 10:23:40 10:30:40 10:34:13 
10:39:47 10:54:33 10:58:43 3:21:59 3:27:38 3:37:58 
3:49:00 4:20:42 4:30:52 4:37:39 4:40:08 4:40:55 
4:42:25 5:03:25 5:10:30 5:10:49 5:12:39 5:14:20 

因此，而不是打印爲了與時俱進，與10點00分時間7點之前來了。

有沒有一種快速的方法來按實際時間排序？

time = c("1:48:55", "1:53:11", "1:58:18", "10:04:01", "10:12:45", "10:14:16", "10:20:24", "10:21:59", "10:23:11", "10:23:40", "10:30:40", "10:34:13", "10:39:47", "10:54:33", "10:58:43", "3:21:59", "3:27:38", "3:37:58", "3:49:00", "4:20:42", "4:30:52", "4:37:39", "4:40:08", "4:40:55", "4:42:25", "5:03:25", "5:10:30", "5:10:49", "5:12:39", "5:14:20") 

time = factor(time) 

Answer 1

試試這個：

library(chron) 
sort(times(time)) 

或者這個，如果你想排序的載體仍然是一個因素：

time[order(times(time))] 

Answer 2

的項目都在他們的順序，所以你用factor，他們將留在該訂單，但你可以設置的方式水平，將讓迴歸報告這些「正常」。如果你想要的時間值，你需要選擇一個時間類的工作他們得到整理

require(gtools) 
mixedsort(time) 
[1] "1:48:55" "1:53:11" "1:58:18" "3:21:59" "3:27:38" "3:37:58" "3:49:00" "4:20:42" "4:30:52" 
[10] "4:37:39" "4:40:08" "4:40:55" "4:42:25" "5:03:25" "5:10:30" "5:10:49" "5:12:39" "5:14:20" 
[19] "10:04:01" "10:12:45" "10:14:16" "10:20:24" "10:21:59" "10:23:11" "10:23:40" "10:30:40" "10:34:13"

：如預期gtools的mixedsort功能將這樣的特徵向量排序。該代下包是一個可能的選擇：

time = c("1:48:55", "1:53:11", "1:58:18", "10:04:01", "10:12:45", "10:14:16", "10:20:24", "10:21:59", "10:23:11", "10:23:40", "10:30:40", "10:34:13", "10:39:47", "10:54:33", "10:58:43", "3:21:59", "3:27:38", "3:37:58", "3:49:00", "4:20:42", "4:30:52", "4:37:39", "4:40:08", "4:40:55", "4:42:25", "5:03:25", "5:10:30", "5:10:49", "5:12:39", "5:14:20")
