通过将向量与数据帧匹配来创建向量[R]

I have the following dataframe:

我有以下数据帧：

> zCode <- sample(50:150, size = 10, replace = TRUE)
> x <- sample(50:150, size = 10, replace = TRUE)
> test <- data.frame(x,zCode )
> test
  zCode  x
1  110 114
2  108 150
3   57 100
4   53  98
5  114  67
6  143 126
7  110  95
8  106 101
9  103  70
10 149  73
