Question

我试图改变我的传奇的顺序，但没有成功。它应该去：S8 S9 S10，但是去：S10 S8 S9。我认为问题出在S10的“ 1”上，我已经尝试了多种解决方案，但是似乎没有任何效果。

我的代码和数据：

将variable转换为一个因子并手动设置级别顺序：

library(ggplot2)
library(dplyr)
#> 
#> Attache Paket: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
