remove duplicates withing each observation

I have something like testDF <- data.frame(v1 = c( 1, 2, 3, 4, 4, 4, 4, 5, 5, 5, 5, 7, 7 ,9),v2 = c("a","b","c","d","d","e","e","e","d","d","a","a","a","b") )

and I need for each obs on v1, to get rid of the duplicates in v2... to get something like

testDF <- data.frame(v1 = c( 1, 2, 3, 4, 4, 5, 5, 5, 7, 9), v2 = c("a","b","c","d","e","e","d","a","a","b") )

any idea on how can I do that??? thanks!

Just use unique(testDF) you than get the following output

   v1 v2
1   1  a
2   2  b
3   3  c
4   4  d
6   4  e
8   5  e
9   5  d
11  5  a
12  7  a
14  9  b
