Computes a weighted quantile of a numeric vector.
# S3 method for default
weightedQuantile(x, w, probs=c(0, 0.25, 0.5, 0.75, 1), na.rm=TRUE,
method=c("wtd.quantile"), ...)Returns the weighted quantile.
a numeric vector containing the values whose weighted
quantile is to be computed.
a numeric vector of weights the same length as
x giving the weights to use for each element of x.
Negative weights are treated as zero weights.
Default value is equal weight to all values.
a logical value indicating whether NA values in
x should be stripped before the computation proceeds,
or not.
If "wtd.quantile", then an internal copy of
Hmisc::wtd.quantile() is used.
No other methods are currently supported.
Additional arguments passed to the estimator.

Internally the following functions may be used:
quantile (if no weights are specified), or an internal
copy of Hmisc::wtd.quantile().
