# wtd.quantile: Weighted Quantiles

## Description

Compute weighted quantile

## Usage

wtd.quantile (x, q=0.5, na.rm = FALSE, weight=NULL)

## Value

Returns an empirical q quantile from a weighted sample.

## Arguments

- x
Vector of data, same length as `weight`

- q
Quantile to compute

- na.rm
Logical: Should NAs be stripped before computation proceeds?

- weight
Vector of weights. If NULL, the default, weights are not used.

## Details

Uses a simple algorithm based on sorting.
