Here's another one: match(d, unique(d)).

Here are a couple more options if you want some variety:
> d <- c(8,7,5,5,3,3,2,1,1,1)
> as.numeric( factor(d, levels=unique(d)) )
[1] 1 2 3 3 4 4 5 6 6 6
> cumsum( !duplicated(d) )
[1] 1 2 3 3 4 4 5 6 6 6
What would you want the output to be if your d vector had another 8
after the last 1? The different solutions will give different output.
