我有一个excel文件,在使用普通read.csv(filename)
阅读之后,其摘录如下所示。复制粘贴导入数据的一列的前16行。
[1] UserName, UserPassword, AppVersion, UserId, UUID, AppId, Latitude, Longitude
[2] UserId, UUID
[3] UserId, UUID
[4] UserId, UUID
[5] UserId, UUID
[6] UserId, UUID
[7] SessionId, StatusId, UserId, UUID
[8] RoomId, Rows, Columns, SeatsRemoved, UserId, UUID
[9] SessionId, UserId, UUID
[10] QueryId, UserId, UUID
[11] SessionId, SeatIdList, StudentIdList, StatusId, UserId, UUID
[12] RoomId, UserId, UUID
[13] SessionId, UserId, UUID
[14] SessionId, UserId, UUID
[15] SessionId, UserId, UUID
[16] MessageType, MessageContent, SenderId, ReceiverId
注意:我使用noquote()
删除了引号。
我需要的是将所有参数值(上面列表中以逗号分隔的单个单词)拉入一个向量(char向量)。我需要一个干净而优雅的方式来做到这一点。通过使用与数据混淆的函数str_split
,我知道混乱的方式。见下文。
str_split(y,",")
[[1]] [1] "UserName" " UserPassword" " AppVersion" " UserId" " UUID" " AppId" [7] " Latitude" " Longitude"
[[2]] [1] "UserId" " UUID"
[[3]] [1] "UserId" " UUID"
[[4]] [1] "UserId" " UUID"
[[5]] [1] "UserId" " UUID"
[[6]] [1] "UserId" " UUID"
[[7]] [1] "SessionId" " StatusId" " UserId" " UUID"
[[8]] [1] "RoomId" " Rows" " Columns" " SeatsRemoved" " UserId" " UUID"
.....
一个整齐的字符向量中需要所有单词。我相信有一种直截了当的方法可以做到这一点。如果您能提供一些提示,请欣赏。
答案 0 :(得分:1)
我认为你在寻找:
unlist(strsplit(y,","))
