[R] Mapping file-Legend- from 2 Files/Tables

[Edwin Sendjaja]

Hello,


Because no one has answered this. I presume that no one knows the soluition.




Fortunately, I found the solution:

Keyword: merge()
----------------------------------------------------------------------
table1<-read.table("Salesman.data")
table2<-read.table("Employee.data")

data<-merge(table1, table2, by.x="User_ID", by.y="User_ID")  


result<-data$Name (for example)

Thank you.



Kind Regards,


Edwin Sendjaja
