提取data.frame中的部分数据（不含列标题和行标题）

 

 ?unlist
    Given a list structure x, unlist simplifies it to produce a vector which contains all the atomic components which occur in x.

unlist(v.row)
[1] 177 165 177 177 177 177 145 132 126 132 132 132 126 120 145 167 167 167
       167 165 177 177 177 177

 

You can do it with as.vector also, but you need to provide the correct mode:
 as.vector(v.row,mode='numeric')
 [1] 177 165 177 177 177 177 145 132 126 132 132 132 126 120 145 167 167
      167 167 165 177 177 177 177
