[R] Quantiles of weighted sample

[Giovanni Petris]

Hello!

I am wondering if there is a function in R that returns quantiles of a
weighted sample, i.e., a set of values, each coming with a different
weight. The function quantile() does that only for the case when the
weights are all equal. 

In other words, I am looking for a quantile function that applies to
a discrete distribution specified by values and their probabilities. 

Thanks in advance.

Best,
Giovanni Petris
