For these two series, I figured out the way to detect the locations of
duplicate values.
Some further tricks will (probably) lead you to your goal. I suppose you
use duplicated() or something similar to get an array of locations of
the duplicated values:
pos.dup <- whcih(duplicated(value))
then do
diff.pos.dup <- diff(pos.dup)
and you get the indices to delete:
pos.delete <- o
