Does this do it for you:

> x <- read.table(textConnection("abc 123 345
+ abc 345 456
+ lmn 567  345
+ hkl 568 535
+ lmn 096  456
+ lmn 768 094"))
>
> x
   V1  V2  V3
1 abc 123 345
2 abc 345 456
3 lmn 567 345
4 hkl 568 535
5 lmn  96 456
6 lmn 768  94
> x[!duplicated(x$V1),]
   V1  V2  V3
1 abc 123 345
3 lmn 567 345
4 hkl 568 535
