## Weighted Median

### Description

Compute a weighted median of a numeric vector.

### Usage

    weighted.median(x, w, na.rm = FALSE)

### Arguments

`x` | a numeric vector containing the values whose mean is to be computed.
`w` | a vector of weights the same length as `x` giving the weights to use for each element of `x`.
`na.rm` | a logical value indicating whether `NA` values in `x` should be stripped before the computation proceeds.

### Details

If `w` is missing then all elements of `x` are given the same weight.

Missing values in `w` are not handled.

The weighted median is the median of the discrete distribution with values given by `x` and probabilities given by `w/sum(w)`.

### Value

numeric value giving the weighted median
