[R] Recall at p plot using ROCR?

Is it possible to use ROCR to plot a simple recall at p plot?  I.e., a
plot where the x-axis is the position into the ranked test set, and
the y-axis is the recall, so you can see what's the recall in the top
10% of the ranked results.

I searched through the performance() manual but found nothing.

(Not a cutoff-vs-recall graph, since the cutoff is the probability
estimate returned by the model.)
