[R] merging two data sets with no column header

[kayj]

Thanks for your reply. 

In your last step If  I create a duplicate ( two similar records )
# create a duplicate 
vv[8,1] <- 7
vv[8,2]<-'g'

and then I merge vv with vv2 ,both duplicates are merged. Is there a way to
tell R to merge only the unique records.

Thanks and appreciate your help.
