which duplicated rows to delete
Hi
Say I've this vector with several duplicates
>x<-c(1,2,3,4,2,6,2,8,2,3)
>which(duplicated(x))
[1] 5 7 9 10 11
But what I realy want is somthing like:
List({2,5,7}, {3,10}, ...)
Then from each sublist I can specify which of the duplicate items to drop
res<-NULL
for(vec in myDuplicateList)
res<-rbind(res, subset(data[vec,], myCrit))
I'll get some of the way by sorting my original data appropriately, as it's
the second and following rows that are 'marked' as duplicates, but that's
not quite enough
Hope for some hints
Kind regards S?ren
