[R] columns mapping

[jd6688]

DF1 
name OTHER 
ABC O 
KKK O 
QQQ O 
DDD O 
PPP O 

DF2 
name 
ABC 
KKK 
DDD 

If the names in df1 resides in df2, then add the mapped name to df1 as a
separate column, for instance "mappedColumn" 

the output should be:
DF1 
name OTHER  mappedColumn
ABC    O        ABC
KKK    O         KKK
QQQ   O       
DDD    O 
PPP     O       PPP


I have been trying for a while, still didn't figure it out, would you please
help if you could. Thanks
