R - 将第一列转换为行名

Question

我正在尝试使用相关矩阵，为此，第一列中的值（Faculty）应转换为行名。

这是数据的外观：

   Row     Faculty                                  Answer Q1   
    1      Architecture, Building and Planning      5    
    2      Social studies                           20 
    3      Law                                      2
    4      Business and Administrative studies.     45
    5      Languages                                53
    6      Historical and Philosophical studies.    16
    7      Creative Arts and Design                 9

这就是我想要的：

 Row                                      Answer Q1   
 Architecture, Building and Planning      5    
 Social studies                           20 
 Law                                      2
 Business and Administrative studies.     45
 Languages                                53
 Historical and Philosophical studies.    16
 Creative Arts and Design                 9

我尝试了rownames(mydata) <- mydata[, 1]

给了我错误：

`(`*tmp*`, value = list(Subject = c("(1) Architecture, Building and Planning",  : 
      length of 'dimnames' [1] not equal to array extent

任何人都知道如何解决这个问题？
