重新排列具有相同值的数据行
重新排列具有相同值的数据行
提问于 2017-01-04 04:43:56
我有以下数据：
Data <- data.frame(Project=c(123,123,123,123,123,123,124,124,124,124,124,124),
Date=c("12/27/2016 15:16","12/27/2016 15:20","12/27/2016 15:24","12/27/2016 15:28","12/27/2016 15:28","12/27/2016 15:42","12/28/2016 7:22","12/28/2016 7:26","12/28/2016 7:35","12/28/2016 11:02","12/28/2016 11:02","12/28/2016 11:28"),
OldValue=c("","Open","In Progress","Open","System Declined","In Progress","System Declined","Open","In Progress","Open","Complete","In Progress"),
NewValue=c("Open","In Progress","System Declined","In Progress","Open","System Declined","Open","In Progress","Complete","In Progress","Open","Complete"))数据已按Project排序，然后按Date排序。
但是，如果有两行具有相同的日期(例如第4行、第5行和第10行、第11行)，我希望根据OldValue指定顺序。所以我想要第5排在第4排前面，第11排在第10排前面。
我该怎么做呢？
