R help - May 2002 - qqnorm() with weighted data?

I've got a set of data that are weighted by a largish integer (ranging
from about 50K to 1.5 million).  I'd like to plot CDF's for this data
taking into account the weighting.  What do you recommend?

Thanks!

I'd use stepfun() in the "stepfun" package.  If necessary, use
aggregate
to sum the weights over unique values and then divide by the total weight
to get probabilities for the observed values, get cumulative sums with
cumsum() and then feed these to stepfun
