将数字映射到R中具有非数值的数据帧

Question

我有一个结构如下的数据框：

C1               C2              C3                C4          C5
Affected User   Affected User   Affected User   Attachment  Affected User
Attachment      Attachment      Attachment      YESIM       Attachment
Description..   NA              Description..   NA          Client ID
Knowledge S..   NA              Knowledge S..   NA          Description..
NA              NA              NA              NA          Knowledge Search
NA              NA              NA              NA          Product Impacted

注意：我已经删除了原始数据框以适应此处，并且还将列名替换为更简单

我有另一个数据帧我想用于映射，它的结构是：

    x
1   Affected User
2   Application Request Variables
3   Attachment
4   Benetrac Incidents
5   Business Critical Date
6   Client ID
7   Comments
8   Configuration Item
9   Contact Info
10  Description / Priority
11  Knowledge Search
12  Product Impacted
13  QEYE
14  Security Incident Variables
15  SVC - Request for
16  YESIM

现在我想将这些值映射到原始数据框，以便它应该像

 C1              C2              C3                C4          C5
 1               1               1                 3           1
 3               3               3                 16          3
 10              NA              10                NA          6
 11              NA              11                NA          10
 NA              NA              NA                NA          11
 NA              NA              NA                NA          12

谢谢

你可以做到

do.call(cbind.data.frame, lapply(df1, match, df2$x))

如果你有完全匹配。
