R help - Aug 2009 - how to plot a gains chart in R?

I have 1000 oberved binary reponses Y, and I also have 1000 predictited
probabilities predicted_prob (between 0 and 1) for those observed reponses.

How can I plot a gain chart in R?

Thanks.

Since I have been clueless about "gains chart" in Google and found
your
  question message within the first two pages of output, I have the 
impression that not very many other readers hearded about it. Reading 
fruther on shows that it might be very related to ROC curves and AUC 
calculations, hence I's suggest to investigate the ROCR package on CRAN.

Best wishes;
