哪个读取或扫描函数用于快速存储来自 excel 的参数转储

Question

我有一个 excel 文件，在使用普通 read.csv(filename) 阅读后，其摘录如下所示。已复制粘贴导入数据一列的前 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：我用 noquote() 去掉了引号。

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（字符向量）。我需要一种干净优雅的方式来做到这一点。我知道使用函数 str_split 会严重破坏数据的混乱方式。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"

.....

所有单词都需要在一个整齐的字符向量中。我相信有一种直接的方法可以做到这一点。如果你能给我一个提示，我将不胜感激。
