What do you mean that you get lots of duplicates? If you have duplicated
entries in df2 this will lead to dups because of the way merge works (here
is the help file):
If there is more than one match, all possible matches contribute
one r
thank you very much!

Hi Karean,
If your first object is called obj1 and the second called obj2, then:
> merge(obj1, obj2, all.x=TRUE)
id trait1 trait2
1 1 10.29.8
2 2 11.1 10.8
3 39.7 NA
4 6 10.2 10.1
5 78.9 NA
6 109.7 NA
7 11 10.2 NA
Hope this helps,
