R正确使用Grouping Likert

Question

我正在尝试让分组选项起作用。当我选择分组时，我得到了错误的数据。以下是我的代码

> likert(GroupCD[16])
  Item Strongly Disagree Disagree  Neutral    Agree Strongly Agree
1  Q16                 0        0 10.71429 46.42857       42.85714
> likert(GroupCD[16],grouping = GroupCD$Group)
  Group Item Strongly Disagree Disagree  Neutral Agree Strongly Agree
1     C  Q16          6.666667 33.33333 60.00000     0              0
2     D  Q16         15.384615 61.53846 23.07692     0              0

因为可以看到分组分隔时的值是错误的，或者我可能(也可能)使用了错误的值。

以下是group列

> print(GroupCD$Group)
 [1] "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "C" "D" "D" "D" "D" "D" "D" "D" "D" "D" "D" "D" "D" "D"

有什么建议吗？

Answer 1

所以我可以结束这个:显然这是R工作区/会话(??)中的垃圾问题。一旦我用一个新的开始，一切都很好
