Question

我有一个这样的数据框（我知道结构有点乱，但我需要它，因为输入数据（Excel）有三个级别的列）：

wait()

我想使用：

将第2行指定为列名

                        NA                     NA.1                     NA.2                     NA.3
1 United States of America United States of America United States of America United States of America
2                  Alabama                  Arizona                 Arkansas               California
3                     <NA>                     <NA>                     <NA>                     <NA>
4                     1225                      399                     1547                      726


df <-    structure(list(`258` = structure(c(3L, 2L, NA, 1L), .Label = c("1225", 
    "Alabama", "United States of America"), class = "factor"), `285` = structure(c(3L, 
    2L, NA, 1L), .Label = c("399", "Arizona", "United States of America"
    ), class = "factor"), `279` = structure(c(3L, 2L, NA, 1L), .Label = c("1547", 
    "Arkansas", "United States of America"), class = "factor"), `340` = structure(c(3L, 
    2L, NA, 1L), .Label = c("726", "California", "United States of America"
    ), class = "factor")), .Names = c("258", "285", "279", "340"), row.names = c(NA, 
    4L), class = "data.frame")

但是，我只获得等级而不是显示状态的角色。反过来也很容易。但是，我坚持了一段时间没有找到解决方案。有任何想法吗？感谢

R：如何获得角色而不是水平？
